up-pipe options for '02 WRX
I have an '02 Rex with an exhaust leak in the stock up-pipe. I am using this as an excuse to upgrade to a non-catted up-pipe and just have a few questions. First off, the setup on the car is a Vishnu stage 0 reflashed ECU, cat-back exhaust, Perrin short ram air intake... as far as I know (I bought it already modified). I don't care too much about extra power, I just want an up-pipe that will last (high quality).
Is it better to go with a flexible up-pipe or to go with no flex?
therefore, Is the Perrin up-pipe or the Helix up-pipe a better bet?
Are there any others I should consider?
One other mod I guess I should mention is that my car has STi engine and tranny mounts... Don't know if that would effect the need for flex or not in the up-pipe.
