07-13-2009, 05:54 PMI cant afford a new muffler for a while so I was wondering if I cut about 2" off the end of the muffler and put the stock chrome cover back on it, will this be OK? I just want to make it louder

07-13-2009, 10:58 PMBefore changing my exhaust for the Xian Racing universal can I drilled some holes in the back and put the cap back on after widening the outlet in it.

It became a lot louder. I suppose you could cut the end off but you may find you have to remove a lot of the internal bits that will be left without the support provided by that back metal wall. (The one I drilled).Jincheng Monkey JC50Q-7

07-14-2009, 12:24 AMIf it shorten the muffler and remove all the internals will it still be safe to run the engine with that limited back pressure? I did drill the holes but it didnt make too much of a difference. a little at idle but thats about it

AF,
What are you hoping to achieve by shortening the muffler? These engine do need some backpressure in the system and if you free it up too much you may find it impossible to tune your fuel/air mixture properly.
It may be easier and cheaper to get an aftermarket.
