Exhaust Drill Out

Hey everyone,

I used to own a 2006 V-Strom and found an article on Twisted Throttle on how to drill out the Muffler for better flow and sound. Has anyone heard or done this on a 2012? I thought about replacing the muffler but I like the Heat Shield and it seems you lose that with aftermarket. Thanks for any advice?

There is one thread here, it's a ways back search for it.

All you have to do is cut the welds, drill out the pea shooter around the hole. Then break the weld down in the pipe. Pull the peashooter out, then rivet the cap back on.

I was thinking about it, but some extra money freed up and I got an aftermarket pipe. Kept the stocker to put back on if needed.

Ear plugs will eliminate the need for that and you'll be spared the comparison to a nit Harley Boy.

Exhaust flow isn't better. Modifying a muffler to increase noise level is illegal almost everywhere so it will hurt resale value. You probably won't run into any legal problems from doing it if it isn't to obnoxious but think about it first.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

Seems I've read on here in the past (pre-2012 models) that many owners have screwed around with their exhaust (drilled holes, etc) and then regreted doing it.........too loud, or backfires on decel, etc. Then they place "Wanted" ads looking for anyone selling their stock systems.........to fix what they #[email protected]% up.

I remember one post about this on a 2012, doing the earlier exhaust mod, and he was extremely disappointed. The result was far from the pre-12 models and sounded only like a bad exhaust leak.

Not a good idea, spend the money and get a real exhaust.

I had an '04 with the pea shooter cut off and the muffler internal baffle drilled out. I disliked both the tone and the level of the sound. I stuck a 1" copper pipe coupling on the stub of the peashooter and improved the tone, but the drilled baffle continued to be too noisy for me. It had no more power than my current non-drilled muffler.

Heat Shield

What about the aftermarket pipes? Any of them come with a heat shield? Won't it get Very Hot without a heat shield?
