We used to make our own silencer boxes for my dad's pickup. But we used old fire extinguishers for the outer pay and welded them shut. lasted much longer, and there was grocery money left after the job. Great video!
I have to give you a big thank you. I pulled out my baffles from drag pipes. I wrapped them with the same insulation you used, it made a nice difference. Not so shard and hard hitting. Thank you.
Too right! Ive always used loft insulation on all my bikes. 2 and 4 stroke. Theres always enough surplice around the edges to pack an exhaust! My current stock is the old insulated jacket from our old hot water tank. Wrapped in protective plastic and cut into thin sheets. Perfect!
Hello Moonfleet41, I just followed your tutorial on my 125cc four stroke Honda muffler. In deed all the soundproofing fiberglass was already gone after two years! Great tutorial. Thumbs up! It' running muuuch quieter now....very quiet.Dude
Thanks a million! I've been watching your tutorials ever since I bought my first Triumph several years ago. Always great presentation and tips. I just bought another T100 and it has the aforementioned (and now discontinued) D&D exhaust. Like you said, they sound great, but they are irritating my neighbors a bit. Exact same echoing sound as your first example. I look forward to doing this modification this weekend.
I believe it sounds much, much more nicer now! When you first installed them I left a comment that I like the sound of the HD more. But, now I can honestly say that its sounds just as nice as the HD if not better! Good on you!
Thanks Abouzar... it's still a different sound to the H-D, not as deep or beefy, but it is much more solid and stronger sounding, which makes me happy! Thanks for watching, Del
Loving your videos. I'm sitting here in the North East of the USA waiting for nice weather. In the mean time I keep learning from your videos. Thank you for making them.
You are most welcome Sir, im glad we can supply some welcome entertainment.. you guys have had the worst winter in years over there, dont envy you at all buddy... hope it warms up for you soon... ride safe, Del.
I found 25' roll 0f 3"x 1/2" fiberglass mat pipe insulation at a home improvement store. one roll was more than enough to y easily, double wrap, two baffles. I secured the loose end with masking tape so it will release and allow loft after run in. Thanks for suggesting building insulation ; my out of pocket was 5USD
I was going to get rid of all the hair this week, clearly i'll just pop round for a trim! Seriously, I had no idea you could use loft insulation! I've plans to put an open pipe on the Enfield, with an airbox mod and rejet (once I've finished running her in. Hitchcocks sell a separate baffle for just a few quid, and it's nice to know I could put to good use the mountain of spare insulation in the loft if I need to tighten the sound up a bit. English pipe with Gold Star silencer, here I come (unless I go for the megaphone!) A welcome return of the 'how to' episodes of late. Hope you've both been having some good two wheel therapy too! All the best RSMF.
Gotta go for the megaphone my friend, there's nothing better than that sound! Been managing to get out at the weekends, just looking forward to it warming up a bit! Be good to catch up with you somewhere this year... all the best buddy, Del
Hey dude. I used to work on a boat building yard. We used to fibreglass hulls of 50 to 60 ft yachts, then fair it down with sandpaper on giant sanding cauls. It was a miserable job to do in summer, in full mask, goggles and a boiler suit. One thing I learnt from the daily splinters and at one point a lung infection, dispite the mask, and that was that you would never get me anywhere near glass fibres in any form without gloves and a respirator with brand new cartriges. I hope you wearnt too itchy after filming this video, five years ago!
learned something new today, simple fiberglass insulation for packing material, GREAT!!! I just saved a bunch of money.... I've got a whole roll of insulation stored away in the shed. Thank you so much for your video!!!
With a new or freshley repacked muffler i always run it outside (go for a ride) i find they blow a lot of fiberglass in the air for the first several miles.
Hi Del and greetings from S Africa. Just watched your video. (Yes I know it's already 4 years old, but we're a little behind the times here). Not so far though. I recently bought a KLR650 and need to look at repacking the FMF can Thanks for the entertainment and the info. Never thought to use gardening wire to hold the packing in place .. Great tip. Keep the rubber side down.
Hi Clive, great to hear form you all the way from the homeland... glad you enjoyed the video, and it can help you out, good luck with yours, and let us know how you get on.. enjoy that new bike, not jealous of your weather there at all ha ha ...first frost of the season here today lol
Hi Del. I bought V&H short shots for my Shadow at xmas, even with the quiet baffles they were still too loud for me, gave me a headache most rides, plus the timing was all wrong, I removed the baffles and re wadded (a word? lol) them, re packed them, took 2 hrs to get the baffles out, bloody things. I still weren't happy, so read up on back pressure, I home made some copper inserts made from flattening some 15mm copper pipe and shaping them into a spring so they wouldn't rattle inside the pipe then I pushed them up into the baffle and secured with a screw on the inside of the pipe so the screw would not show, this gave just the right amount of back pressure to reduce the noise to a more pleasant sound for the rider, but also gave more low end torque and reduce the backfire too. I learned that straight through drag pipes are good for drag racing as they gave the best top end, but for simple everyday riding this can just be a pain and give most riders a headache, I still love the sound of the pipes on my bike since the home made baffle inserts and a lot of people have said that it sounds much better, a more lower sounding rubble rather than I barking sound, this is before I've explained what I've done to improve it. I know too much back pressure is bad for the engine, but it seems to be spot on at the moment so I'm very happy with it. Enjoyed ya video, thanks guys. Paul.
Well done Paul, i love the sound of that mod to bung up the pipes a bit, you're right, you can have too hollow and empty a sound, and a little baffling can make a huge improvement. Thanks for sharing that buddy, ride safe and enjoy your bike.. Del.
Sounds good, a little deeper. I'm ran open pipes last couple of months I rode last year, going to put the baffles back into it this year before I take her out, and I think I will pack the cobra pipes and see what they sound like. I just have to come across some insulation somewhere, maybe at a construction site.
Vidal Delssoon working his magic with a pair of scissors, pink Hi Viz, curlers and plenty of hairspray lol Yet another great vid Del, although no more loft insulation left, could be a cold next winter ;-)
ha ha, one of those nice silk scarves ties to one side...mmm ducky.. and you know lofts.. never looked in one and not seen that predictable half roll left over chucked over the back...lol good to see you today buddy, thanks for riding all the way down, nice lunch, nice company and look forward to the next one.
this is ace! ... i have a as yet unidentified yoshimura exhaust on the dr650 i just boight. I really want o over haul the whole thigs.. so this is goona be very helpful.
Years ago, I "fabricated" a fiberglass packed baffle tube to stick on the tail end of the expansion chamber on my brother's 2 stroke motocross bike. The thing was too crazy loud for riding around in our neighborhood. I'm sure the engine wasn't very happy with the added back pressure, but it ran ok, and was WAY quieter ... for about 5 minutes. That's how long it took for the whole thing to shoot off into the woods somewhere. Good times!
Ha ha, thats the kind of memories that growing up is made of....nice tail mate, and i think we all did that kind of thing at some point...usually begins with the words.."I know...what about..."
.....something for the weekend sir? going anywhere nice for your holidays???.......nice to see Timmy Mallet come out to play! I remember taking the wadding out on my Fresco on my Fizzy.
Yeah, you're not wrong mate, the other end of my biking life I was pulling baffles out and cutting them in half, now I'm packing them back up again!... next I'll be buying kevlar cardigans... !
Do the bikes run hotter though del? I’ve used exhaust wrap before on the baffles but loft insulation is a great idea but just don’t let insulate Britain know 😉
Miss Penny, he sure like the hair scissors a little too much. So if he starts to swish when he walks or talking with a lisp.. Look out... Just kidding.. We love your sense of humor. Thanks for the video.
Thank you kindly Ed... thought he did it a bit too well actually lol! ...Although it will be a long time before I let him near me with a pair of scissors haha!... am happy to let him just fix my bike for now... ride safe, Penny
Great video Del, I honestly thought I was the only one to do this, lol, My dad told me what to do years ago, thankfully It's not a job I've had to do many times as that stuff makes me itch like crazy, RSMF.
My Z 1000 sounds like a tank with the baffles out, wonderful sound! But use wool baffling and still tad noisy, and every time i go for an MOT get told its too loud, don't know how to make it any quieter?
Hey Del. Just a quick question about soldering. After watching your vid using solder as a filler, I thought I might try it to fill pitted fork stanchions. I use super glue to fill and fine grade wet n dry to sand at the mo but it needs re-doing every few months (its only a 15 minute job). Do you reckon solder would bond well? Otherwise I'm thinking epoxy or some such. Your thoughts would be much appreciated.
Well if you're bodging the pitted spots every few months, then i guess it cant hurt to try, i have no idea if it will stay put...have a go and let us know.... but long term, why not get them rechromed..?
Moonfleet41 Unfortunately the budget doesn't allow for re-chroming for a while yet. Spent a small fortune on this old bike so far this year and unfortunately the missus is putting her foot down and wants a holiday and some new soft furnishings! I'll try the solder but above the point the fork seal travels to test, and do the rest if it bonds well. Let you know if it works out. Thanks as always for your reply mate.
Great little vid,Sounds much better del,lot deeper, doing the loft soon so I'll be sure ta keep some to the side for the future, on another note,have you any what the legal DB level is,I keep getting different answer's.Lee.
Hi mate....there is currently NO legal Db limit for road bikes, they rely on the enforcement of "not for road use" stamps etc and 'tollerate' louder cans as long as they are not ridiculous....most race tracks have a Db limit for track days, it varies around 103 and a perceived pitch..(screaming two strokes need to be much lower)... but for the road, we have got away with that legislation so far..!
Thanks for the video, this will save me a lot of money i know it. Just a quick question, I have some woven fiberglass cloth laying around and was wondering if i could just wrap that around instead or will i have to go out and find some insulation to wrap it with. Thank You and keep up the great work
shane man The packing needs to be absorbant to absorb the sound resonance...im sue if you used a sheet wrap it wouldn't work the same...but hey, why not give ti a try.. nowt to lose if you already own it!!
I've still got a lot to learn about from you about biking so I don't want to lose you to some saw or piece of garden equipment mate and if I don't look out for you who knows what kind of trouble you will get into. CHRIST I sound like your Dad LOL
Nice one. Quick question: does the packing deteriorate over time, over useage or a combination of both. I've got a race can (sounds luuurverly with the V-4), it only did a couple thou on the bike every summer but it's probably about 8yrs old now. Time for a re-pack?
Yes indeed, quite correct my friend, they do deteriorate over time and use, the tiny fibers of wool break up and disintegrate as time passes and they get louder and louder... the problem it that its so slow and progressive that you wont notice it getting louder...however, ill bet that if you take the baffle out, after 8 years, you have hardly any wadding left, plus it will also be very gummed up with soot and condenstation that it wont be very absorbent now and it needs to be t absorb sound..But once you repack it, you'll notice a marked difference right away... hope that helps.. Del.
Moonfleet41 yes, i am even sat with a cup of excellent tea and one of Mr Kiplings exceedingly good cakes (a banoffee toffee one by the way!) watching this excellent video :D
Pro Tip: open garage door when running indoors, carbon monoxide can harm you. Also dont run engine before touching exhaust it will get hot. Wear neoprene gloves so ya won't itch later. That is all.... lol
Hi. Would you recomend the Triumph (Bonneville T100 Black ) as an only bike and only transport, bit of commuting / shopping / days out etc.? Looking at getting a bike after a 6 year break and prefer the look of the round head light. Cheers
I certainly would mate, sounds like a perfect choice, they were once upon a time (referring to the original Triumphs) the only bike a bloke would own, and he would do everything on it, Trot along to yer local dealer and take one out for a ride, you'll soon see what i mean... unless you want speed and performance its your perfect 'everybike'...
Yes Adam, that would work fine as long as you dont drill the holes out too big... also you can simple re-rivet the cap back on too....good luck with it..Del.
Hi Del and all! Thank you Del for such a channel; learned a lot because of you ! I have some questions: Nightster 1200 , 2007. Slip ons Screamin Eagle. Took them out; almost no more insulation. My baffle has a strange inlet in it that deviates the gases in between the OD baffle and ID of the chomed pipe. Not modified. The baffle is drilled with almost 3/8 inch holes. Not many though. Nothing compare to a lot i saw on your channel or others. A drawing would be easier... Anyway; I wrapped everything with alumina blanket + fiber glass (like yours). No more backfired sound, and all that bad noise, but still super loud. Can you tell me something about that deviation ? I clogged it with the insulation: starting to think was stupid. Should i drill more holes or by another set of baffles ? Cheers mate.
Just to be clear buddy... what are you exactly trying to achieve here?.. more power?, more noise?, less noise?, maybe to pass some kind of smog test?... not sure what you are asking buddy... !
Must admit, not really clear. Well : much less noise. The damn thing is loud like Hell. Power, i have plenty. Do not want to put back the stock exhaust. I have a Screamin Eagle breather and a remap... Not dyno ($$). Need to lower the dB. I am wondering if i should drill holes in the baffles so that the insulation traps more of the sound. Also, my question was also theoretical; what is the purpose of that deviation done in the baffles? Generally, the baffles are just plain tubes drilled. Have you ever seen that kind of baffle? Did i made a mistake by putting insulation everywhere (and at the same time, covering that deviation)? tx for all
Hi Del, another great video. Thank you. How far you have come in these few years 🤣. I am about to buy a 2001 Triumph Speed Triple...but, please don't spit your cornflakes out, it's too loud! So I was going to look at adding/replacing the baffle and/or packing like this video. Do you know, does anything else need doing regards engine management if you do this? I heard someone mention 'ecu will need remapping' which sounds like I won't have the necessary hammer! I would value your opinion. I'm just a sedate commuter, not a wheelying nutter! Cheers!
Hi Daniel, It's difficult to answer that mate as not sure what exhaust you have, does it currently run smooth and clean right through the rev range to the red line? If so, then you're good to go... you will have to find out if it was re-mapped to get where it is (previous owner), perhaps there's evidence in the history? If you wanna go back to a more standard factory sound, then the Triumph dealer can re-map it back to factory for you... and if there's no evidence in your history, they can tell you what map is currently installed, so it looks like a trip to the dealer at the very least... but they don't charge much and they'll do it properly for you!
@@Moonfleet41 thanks Del, but I'm confused. I collect the bike tomorrow so will check the history for any evidence. But I guess you are saying that, whatever I do - new exhaust, repack...I need a visit to the dealer to check or remap...?
@@danielb1563 No, im just saying to check what you have in the bike right now.. if it has an open loud exhaust then it would most likely have been remapped for that in order to get the best from it.. if it has an open race can on it, and runs smoothly right round the clock.. then it should do the same with the pipe repacked.. just ride it once you have repacked it and see if it pulls and rides smooth with no flat spots... and if you find any flat spots or it coughs at certain revs, then it could be worth a look at remapping it..!
@@Moonfleet41 thanks Del. I got the bike this week, and actually spent an hour or so at Hughenden M40 Triumph yesterday and they really explained, as you have about it too... I may refit an original exhaust - at least for a bit. They said it'll likely run rich, if I do. Which is better than running lean...but see how it goes. Thanks, I am loving the triple!!
Hi del great video .. I've started using TEC 2x2 clubman exhaust on my Bonnie in place of TOR exhausts. But it sounds timid with the baffles and very loud n tinny without the baffles. How do I adjust the baffles for a more rich bassy beat just like that with the TOR exhausts. Do I shorten the baffles or cut open up the end . Need your expert advice on this . Thanks and regards.
Hi Kumara. I am friends with George Milburn, the Owner of TEC Bike Parts, and i was involved way back when he first designed the TEC exhausts, the baffles he designed we're meant to be really quiet just like the factory pipes if you wanted that, but you could cut them down to tune the sound as you wanted... so if it is the kind that are 'capped off' at the end, with a few holes round the tube.. then you could first cut just the cap itself off leaving the tube long, but open all the way through.. and see how you like that.... if you want more volume and a deeper sound, then you can cut the tube down in short increments until its right for your taste... Hope that helps you my friend, good luck with it.. Del.
dunno why im watching this i already did it to my bike. I would advise people to wear gloves of any kind cos the fibre glass is so bloody itchy on skin
Just put Short Shot slip ons in place of the mufflers, retaining the stock header pipes will be nice and loud, with no other mods needed, but if you do add a fueling device and open filter, you'll gain lots more power and the bike will run cooler.
Wow that does sound much nicer, roof insulation, ill remember that :-)) Near the end it did look like donna kebab meat on a pole lol :-) Smashing tip :-))
Hi Del...why don't you just remove the packing all together , aye? (eh)?Loud pipes save lives!! lol.".you know its gonna knock your bloody teeth out"..lolluv it..your the best Del!!Oh I see less tinny sounding...yeah I got it!! much bassier!
Are you related to Gordon Ramsey, ..or you just sound like him? At least no swearing !! Even rolling the Glass like a dough. Very good. Wearing gloves and using a mask a must. How much is a Haircut?
