I have a PX with some porting etc, and I have been using a Sito Plus exhaust.
Two problems - 1) After about a month, the noise is really annoying - not just loud, but painful. 2) After a few more months, the thing is so rusty it needs replacing.
I ride all year, so this is getting expensive - two exhausts a year is adding up!
Any suggestions? I dont want a pipe that sends all the power right up the rev range, but I do want it to sound good, add power, and LAST!!
Thanks for any advice, Nick
