Interesting test... but I also wanted to see HOW the eBay baffle were INSTALLED... EVERYONE says its really "easy" yet no one is SHOWING it, and if there is drilling involved. - I need a set of baffles for pipes on a second hand bike, and the seller TOTALLY removed the RoadHouse baffles. #$%&
Amazing difference. Fuck sound quality- Tinnitus Is PureHell. At some point after you turn 50 your gonna pay dearly for every single loud exhaust you ever had. Nice work DOL.
@@DriveOnLeft Nice- but not just for Motos. Also heavy equipment, hand Tools power tools ,chainsaws- leaf blowers -riding in tractor trailers- riding on highway or city traffic with widows down being just near idling running bikes a lot or near city traffic- barking dogs,slamming doors, emergency vehicles- trucks backin-up that warning beep will damage your ears in no-time. ect and At work when feasible- The list is truly endless but oh well the consequences of catastrophic tinnitus are 80 plus DB of screeching in your Skull every second of every moment for life- no breaks or time-outs. None. And crying mommy won’t help I’ve doing it for 6 years every single night between 2 am and sunrise. Because your certainty never going to experience what others call sleeping ever again. Not with a fire alarm and churc n Bells ringing in your head. And it always gets worse NEVER better- because your always gonna slack and have little fuck-ups that actually are not so little. Even loud electric head shavers transit that noise thru your skull to you ears or using the fucking vacuum cleaner and the lawn mower and snow blower- I’m telling you mark my word. Musicians and riders don’t want tinnitus at all cost. It’s a game changer and your probably real close to getting it unless you start wearing the f cheap Macks Orange plugs religiously and properly which means shove them in deep. They from fromfucking Walmart who knew. Those plugs are as a good as any for now and easily assessable for anyone please trust I spent hundreds over the years. Best wishes. Don’t let heathens rob your hearing- if someone beeps a horn or revs their loud exhaust while your 2 feet from their vehicle hurt them mercilessly. But if you do the right thing starting now you may never have any issues or you will be so prepared when it does start that it wil. Never get beyond mild level which is nothing compared to a sever case.
If you are going to put these on a cheap slip on, weld them in (Or Red loctite them on the edges they seat at, if you don't want to weld)! I read reviews of them flying out on the highway. Also use Threadlocker (Red Loctite) on the threads and add a washer to prevent it ripping that out as well. Mine stay seated for like 5K miles, so NGL that's a win so far.
About that cheap baffle. Is there any difference in the sounds if I move that screw cap a different position on the baffle if baffle is little longer about 140mm ? Why there is these adjust holes anyways?
Mine works fine on my C50 Suzuki. But...the bolts rattle loose so I would use a nut and wrap it....to reduce rattling...then later the baffle Tube broke off...just after 50 miles.
I was going to order baffles from the company that made the pipes and they wanted way over $100 for 2 so I got the cheap Chinese ones of Amazon for $30 and got them overnight put them in and it’s a done deal nice and mellow sound
I understand having a quieter exhaust , but what does it do to the power, we all know blocking an exhaust like this will reduce power.. but by how much?
I wonder if it would just take it back to stock power. The stock exhausts are very restrictive through out the exhaust. These baffles only restrict it at the exit. Would be awesome to see dyno results though
Exactly...if it restricts air flow what effect does that have on performance? What's the point of paying 100s on an Akroprovic to then bung a stopper in the end and potentially make the exaust unable to deliver the performance improvement...might as well stall OEM.
Just a tip - we usually make such measurements with A-weighting on (so it responds a lot like our ears.) I suspect your reductions seem greater in number than it sounds because it was measured in dB not dBA.
Awesome Video! I have been looking for Baffles for my Set of Ultima Big Growl, Non-Baffled Exhaust. And, I have considered trying out the eBay Baffles. Now, I will... Thank you for this Video. :-) Peace, Stiletto :-)
Tried a 51mm short dB killer on cheap ass SC Project knockoff. Sound was definitely quieter than before but damn i feel like the engine is slow to get to top speed and needs to rev higher. So i decided to make the holes bigger and test the whole thing. If it's good then I'll dyno and remap my bike.
Did the straight baffle fit into the end can ok? I have Akrapovic exhausts on my bike with the very end of the can angled like yours, but I didn't thing a straight baffle would fit in ok?
I am just about to find out this morning whether my Lazada, even cheaper baffles work enough to keep the cops off my back in Thailand on my Honda Shadow.
@@DriveOnLeft I am curious If full restriction means cap at the small end, or closer to the big end? I ordered what I hope will fit my M4 GP exhaust which is extremely noisy and actually just a Chinese version (my bike is a R6). Most of the baffles are roughly four inches, this one being five.
@@Ro6entX really? What do you think ... Air restriction.... The less holes between moveable cap and big side, the less area for the air to pass through, so more restriction.
I had a BMW F650 with a Dominator aftermarket exhaust that was extremely loud even with their optional “DB Killer”….that did not kill much sound at all. I also have a DR650 Suzuki with a Delkelvic exhaust that was also loud for my (and the neighbors) taste. I sent off for a Chinese Ebay db killer for both pipes and they were less than $10 USD each. Both were about 4” long with a movable plug to adjust the sound. They both arrived and both fit in the pipes, one with only a bit of filing to remove a burr. They both worked fine and reduced the sound notably. Only in the extreme position did it affect the performance. I also went a step further and made matching movable cups to increase my adjustability and that worked out even better still. I tried to add fiberglass to wrap the stinger several times but in just a few days it either partially melted or compressed on one end of the stinger and got loud again. I wanted to also add some sort of spark arrestor as I live in a dry fire prone area and I took a stainless steel kitchen scrubber pad and wrapped and wired it in place around the stinger. That even worked better still and almost stopped the occasional popping in deceleration. Overall, it was a 100% success. Cheap, with adjustable sound level, easy to install and modify and still had a quiet but pleasant tone too. 👍🏻👍🏻👍🏻
@@worldofwoodrow3192 Could explain in more detail and send pictures but do not know how to contact you privately on this UTube thing. Not only was db reduced but the stainless mesh certainly contributed to stopping any sparks but reduced the popping on deceleration a huge amount. I would guess 85-90 %. On the Dominator pipe it would occasionally send out a backfire and flame…..a big no no in fire prone country and I had to stop riding off road with that pipe or risk a fire. Also the resulting tone of the exhaust note improved, very deep growl, not a high pitched bark. This was a plus, plus, plus modification, big improvement with minimal (if any) power drop after I experimented with the right two cap placement on the Ebay db killer I got. I no longer own the BMW Funduro with the Dominator pipe but I got a Delkelvic pipe for my Suzuki DR 650 which was also too loud. I duplicated the same mod on that pipe and it worked the same way. 👍🏻👍🏻👍🏻
@@dogfeathers5646 This comment is gold. I'm going to get a ebay silencer and a mesh scrubbing thing like you mentioned and try it. Thanks for posting this!
@@Raptorlifts There is a bit more to it than just buying a baffle and stainless scrubber pads to get the results I experienced. It was cheap, pretty easy, and worked well, but it was not just buy, install and you are done. Wish I could figure out to privately respond and explain with further details. Good luck and the ears of the world thank you for trying.
I end up using one for my M4 (replica) and while it was still loud, it was few db less than before. I tried the fiberglass truck and worked much better but was concerned about possible engine damage so I removed it.
Fitted one of these but it was the longer version to a scorpion exhaust on my old zx6r and it made it quieter than stock! So really good in terms of sound deadening. However it did rob some power of the bike.
Really to be more accurate you could've measured it at certain rpms, so idle, which is usually 1000, 6000, because that's usually when you're power band kicks in, on Yammy and Kawi sports bikes, to my knowledge anyway, and then something near the redline... That gives you, us, a more accurate measurement, but still, your results were pretty conclusive, good job sir 👍 and thanks 👏 And also it would've been nice to test various designs to see which designs improve the quietness of the exhausts, I've just been watching a guy dabble with his own designs on a car exhaust and his designs were pretty well thought out, also including like a pulled back of the fumes, i guess not only to make it quieter but also make it outperform other designs, pretty intuitive stuff 😉
do you know if its okay to put these baffles in the exhaust where the midpipe meets the slip on? I can't get a baffle to fit in the end of my slip on but it fits fine in the end that meets the mid pipe
Very late reply.... but YES, that's perfectly fine and safe to install a baffle at the pipe/ muffler joint. As a matter of fact, that's where many manufacturers install their DB killers. 👍
