Premium Member freeman Posted February 2, 2015 Premium Member Share Posted February 2, 2015 Quick question guys n gals. Has anyone heard of removing some baffles from the stock muffler? I would be willing to do this for the purpose of adding more noise and not necessarily performance. thanks Link to comment Share on other sites More sharing options...
Guest whitegas Posted February 2, 2015 Share Posted February 2, 2015 I have no clue if the stock exhaust mod has removable baffles. Willing to bet, the entire thing is its baffle. Refer to this topic for some stock mods, I think the guy just drilled a few holes or something. Unfortunately the youtube clip in the thread doesn't work. http://fz07.org/thread/795/stock-exhaust-mod Link to comment Share on other sites More sharing options...
Guest August BB Posted February 2, 2015 Share Posted February 2, 2015 Yeah, looking at the assembly, not much you can do. http://www.yamahapartshouse.com/oemparts/a/yam/53a99b1af8700220a44158c0/exhaust That protector assembly isn't doing any baffling at all.

rotaryryan24 Posted February 2, 2015 Share Posted February 2, 2015 I thought long and hard about moding the stock exhaust. I even picked up a spare to play with, pics here. In the end it was easier for me to just make my own. You do or don't Then your dead.

Guest August BB Posted February 2, 2015 Share Posted February 2, 2015 Haha. Holy crap, I never saw that topic of yours. No wonder that thing is so quiet. Double baffle! Link to comment Share on other sites More sharing options...

scordiaboy515 Posted February 2, 2015 Share Posted February 2, 2015 .....IMHO, don't waste your time. $400 bux gets you a M4....sounds and looks great and saves 9 lb's Link to comment Share on other sites More sharing options...

Any performance gains are small just as any other exhaust. You do or don't Then your dead.

paulibiker Posted December 17, 2015 Share Posted December 17, 2015 I know this thread is old, but I ran a 1 inche hole saw through two baffles/chambers of the OE muffler. Still quiet at cruise with a little bite on the gas. Link to comment Share on other sites More sharing options...

topazsparrow Posted July 14, 2016 Share Posted July 14, 2016 Sorry, double post..... just did this Did this a few weeks ago with a hole saw - ended up being about a 3/4 inch hole. posted it here: http://fz07.org/thread/5173/drill-stock-exhaust?page=3 It sounds much nicer at idle (no more moped sound). When you're accelerating the difference is pretty negligible though. Link to comment Share on other sites More sharing options...
gregjet Posted July 17, 2016 Share Posted July 17, 2016 Ralph you are a little gem. Thanks for that . I always wondered how they had configured it. Useful to know if you are racing in a class that allows muffler removal but headers have to remain. The collector is actually not to bad inside to attach a tail pipe and can, if you strip the shell off. Go forth and modify my son...go forth and modify...
