Mark,

True GPS reading as a matter of fact. I know the shop mechanic said he thought it would give the stock 500's a run for the $'s. I was surprised too because it FELT allot faster. I KNOW it's much faster than a stock Boss. Do a good GPS reading and see what you get on your Boss?

i have a 03 trailboss i cant seem to find any after market exhaust for it any help would be greatly appreciated.

 

NIGHTFLIGHT, Call Rick at RCR, (618) 644-3211 and ask for the White Brothers E series slip on. Make sure to triple the heat reflector tape in the side panel and add tape to the inside of the fender etc.. Center the pipe and exhaust through its path. Locate the exhaust end just forward of the rear grab bar to protect it when you back into things. I don't think you'll need a heat shield at the disks if you place it just in front of the grab bar as it exausts back and out from the disks. Follow the instructions. All this worked great for me. Be sure to get the Forest Approved Spark Arrester - Total $250.00. Quite a bit louder than stock. Lukester
