Harley Sportster Exhaust Drill Out Baffle Mod 

why didn't you start it so we could hear it? seriously?

Thank you for the post. I just did this to my wifes bike and it sounds great. I almost got cut off in a parking lot. One quick rev and the car jerked to a stop. I love the sound and the price is nice.

Sadly the bike has been returned to the original owner. I've read the comments and the reason I used the tapered bits is that I could stop and test the sound at different hole sizes, I didn't want it too loud. As one commenter was offended by any noise, I can assure him it wasn't too loud. We like enough sound to be noticed but not enough to scare people. This mod is perfect and makes the bike sound like it should. As far as the view that loud pipes don't save lives, I have been riding for 32 years and will swear in court that it does! Do you always believe what other people tell you?

I drilled 3/4 inch holes in the baffle on my 04 sportster 1200 using this same method. It sounds pretty good! I made a video with the sound so you can hear it.

What do you mean Pointless??? Its an excellent way for an average DIY'er to mod his bike to make it sound better. The only tool needed is a hand drill and 10 minutes of work. I didn't post audio clips as it's useless, I can't tell one clip from another when judging mufflers on RU-vid and posting DB levels is useless too as most don't know the difference between 85 and 90 db. It works, it's cheap, it's easy and worth it.

Hi Thanks for the video. Little feedback. Machinery Handbook specifically said not to use 3-1 oil for cutting, drilling and tapping operations. You should use a Sulphur based oil. That's why thread cutting oil smells like sulphur. They even recommend lard as an alternative if you don't have cutting oil. Thats also what makes some stainless steels machinable and others not so much; a higher sulphur content.

Thanks for taking the time to get this up here.

Thanks for sharing this , not sure why there are so many dislikes. Dang trolls. I got them on my channel as well. THANKS BROTHER IN CHRIST 🙏🔥💚

I used a 1/4 inch metal 12" drill bit and gently hammered it through ran it and though it sounded much better, I then used a 1'2 inch size drill bit and again hammered it through. I gotta say it's is way better and sounded really nice and deep. I am happy with it. I bought an 05 softail efi.

you should most definitely take the mufflers off, and clean the inside out for metal shavings made by drilling, exhaust isnt just gasses going out, while throttle is decreasing (deceleration) a vacuum is created and metal shavings could potentially (but not definitely) be sucked into the engine... just a caution from an auto mechanic and Harley owner. deff agree about using oil to drill, it also will decrease the temp the metal you are drilling therefor decreasing metal fatigue and distortion.

Good video, I used a 1 1/4 hole saw. Worked like a charm. I too, was considering the entire baffle removed. Glad I didn’t, sounds just right for me.

Weird thing is that I did exactly this today and did.a search to find out whether someone else also does it thus way. Only difference is that my pipes were off, as I had a really loud custom pipe made. I like this drilled restrictor better.

I’m glad you said that , so I won’t bother watching the rest

Looks easy enough but it's pretty easy to take off the slip-ons and then you aren't leaving all the drill shavings in your pipes. Just my opinion, thanks for the video

Nice bike! Thanks for sharing, I drill mine the same way using step drills works best.

Thanks and nice job explaining the tools and process! Can you maybe post a video of the bike sound after this mod? I want to try this mod first before dropping a grand at the dealership for stage-1 upgrade on my '08 Sportster 1200 Custom.

thanks ; got a 2005 deluxe and will do the same. Pretty much the same exaust.

Cheep skate... get you woman a nice set of Vance and Hines

I wish I would have found your video before I tried to do my mod. This seems to be the best way to mod tapered pipes. I took mine off and attempted to mod as if they were straight pipes. Did not work. I'm going to use this method.

LOL I knew he was from Canada when he said aboot JK cool bike

Is this bad for the bike in any way?

I hate these videos of them talking forever and never starting it

Great video. Thanks very much. Did you do it to only one pipe or both? Thanks

should've used a hole saw the size of the inside diameter of the pipe. Then just pull the baffles out without removing the pipes. Easiest way to do it.

Would have been better if we could hear it.🤔

basically basically basically basically

here's a easy mod: Easiest Exhaust Mod to make your pipes louder

the ole ladys big is lookin good....

Would've liked to hear it, why didn't you start it up?

Nice video. Have you ever measured the decibels after the mod?

Are those 8 inch handle bars

I did the same mod to my bike. And it sounds great! I also like the color you used on the bike. Can you please give me the name and the color code? Thank you

What year is is? And is it conrad purple?

Phukn Canadian.... start the damned bike so we can hear it!

no before and after sound examples ...

I woupdnt run the bike after leaving metal shavings that close to the head pipe and jugs, id take the muffs off. Hate to see it suck in any junk

what year was the bike? Is it fuel injected?

Engine start at..... Oh wait.

Is there a way to reinsert them for inspection?

owwt

u gotta be from the 6 ay

This guy put a 1/2 inch hole ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WoPkKxu60Iw.html you put 3/4 would be nice to hear the end result and report on performance too. thanks

SOUND MEANS U R LOSING POWER. SMOOTNESS REAL RIDING PLEASURE. BURNING OF VALVES. LOW MILEAGE. HEATING ENGINE BADLY. NEVER MODIFIED EXHAUST SYSTEM AT ANY STAGE. READ TECHNICAL REPORTS AND JAPANESE SPECIFICATIONS.

And NOBODY has a clue if it worked or not because you didn't start the damned bike

What a waste of time

5 minutes of my time I 'll never get back... didn't even show the baffle being removed.... Canadian....I should have known better. waste of time

man....waste of time watching this

Pointless!!!!!
