I'm sure this question has come up in the past, but I need some new ideas. I have an 04' wrx and I want to get an up-pipe. I'm not sure which up-pipe I should get. I know that the sti comes with an up-pipe that has no cat. If I was to get that, would I be able to still pass smog? Do any of you guys have suggestions or websites that I could go to? Could you also let me know roughly the price of an up-pipe? Thanks!

 

wouldn't know since EJ25s don't have up pipes.

 

Try posting in "WRX powerplant"
