Re: [ST] Real <proven> benefits of triumph performance exhaust?

["STeve Duncan" <xhippy@xxxxxxxxxxx>]

In my experience / opinion a change in the muffler (aka "can") rarely makes 
any genuine difference in performance.  To get any real boost you would need 
to change out the entire exhaust system (i.e. headers, pipes and muffler) 
and have it tuned to the particular motor.  That being said, a change in the 
muffler can smooth out the torque curve somewhat on modern bikes, given the 
EPA mandated noise / emissions standards.  What an aftermarket can really 
gives over all other factors is a really cool ~sound~.  It makes the bike 
sound like it "should", nothing more, nothing less.  So fergit about any 
real performance gains and enjoy that sweet triple howl.



happy trails,
