I searched old posts and read about the exhaust mod for the 660 Grizzly, but couldn't find anything for the 600. Is there a comparable cheap/free mod for my '99 Grizzly? Thanks in advance for any help.

 

As an old tuner, best not to screw with the factory settings unless you're up in the mtns. That thing ain't fast enough fer ya? Yeesh man, I want more muff so I can ride this thing 24/7 and not **** off the neighbors or deer... It's scary fast as it is for what it is.

 

Thanks for your reply. I've come to the same conclusion after riding the Grizzly for a while. Lots of solid power as-is.
