Hello. Just thought i would throw out this question for all you exhaust guys. Until i scoop up enough money for an exhaust is their anything i can do to my stock raptor 02 660 pipe or muffler for performance gain or better sound? thanks, scarface

 

Yeah, throw it in the trash, you get more air doing that and it sounds better rattling off the inside of the can. Seriously, if you dont have the money for a new pipe, the guys on this forum probably have a used systems, header and silencer you can pick up for a fraction of a new system. You need a new high flow filter, I suggest pitching the stock filter and getting a pro design manifold and k&N filter. Then you need to rejet. Good luck, someone on here has an exhaust system for you.

 

Thanks i appreciate the info.
