Stock exhaust mod?

Recommended Posts

My bike is completely stock and I want a bit more noise for when I am racing as I can't hear the engine when up against other bikes.

I tried it without out the baffle but it was too much. Was considering cutting the baffle down slightly.

Has anyone done this and what were your thoughts?

I don't want to buy another exhaust or do the airbox mod

04-07 250X:   Remove the baffle, look at the 2 flat black discs (part furthest from the exit hole) they are attached to a small diameter pipe/tube with a couple holes in it.  Take a hacksaw, cut that pipe/tube at the holes.  Discard the short pipe with the 2 flat discs attached.  Reinstall the now shortened exhaust insert.

 

Result, a bit louder than stock but very reasonable sound and better flow.

 

Or you can get a 08-13 stock muffler endcap off ebay.  They are a bit more open then the stock earlier model endcap.

Thanks, that is what I was thinking but wanted to see if someone had done it before I cut it down.

I'll do some before and afters with a db meter I have on my phone

My iPhone app stock without the baffle read 98db. I don't know about the accuracy but the customer ratings stated that the app was spot on with a pro meter. The app was "Decibel 10th" for iPhone (free).

Just downloaded it.  Awesome little tool!!!
