03 400 manual exhaust mods.
#1
Can anyone recommend a bolt on exhaust tip which will work on a 400 manual to will improve power and torque without doing alot of carb work?
My machine is stock except for the K&N airfilter.
Appreciate your help.

gut your stock pipe by cutting off both ends and then knocking the baflle out with a block of wood and a hammer. Be sure to get the housing back in the same exact place or it wont bolt up right.
