Is there anything i can do to my stock grizzly exhaust to get any extra performance?

 

Yes there is a stock exhaust mod but I don't know how to do it. Check out highlifter's forum, there is plenty of info there about it.

 

You can take the spark arrester out and replace the end cap, but it will only be louder, you won't gain much if any power.

 

well got boared at work today so i pulled tail pipe of the grizz cut the little pipe out and welded a 1 3\4 pipe in reinsalled spark arrester
o yea i also drilled 6 1\2 holes in baffle played in parking lot with the 27 inch mud lites the front end comes off the ground put in low and she realy comes up cant wait for the trail it has a nice rumble to it hope it is still under 96 decibals [limit in wisconsin]
