I did add some mods but not anything major in terms of serious performance (K&N, 17" wheels, and resonator) on the CSVT. I guess I'm past that stage in life (so my wife says)

; my CSVT is essentially a kiddie/grocery getter.
My Firebird is the benfactor of mods such as chip programming, valve job, exhaust goodies, baer brakes, suspension goodies. It's a very strong car but its not pratical for everyday driving.
Did you have any installation fitiment problems with the SHO ypipe?
