definitley get the Autosport Catback, or even better, the SPT. ifyou havent realized, cops here are total assbags. the AutoSport has dual tips and looks stock. the SPT is cheap(around 450) and is full stainless 3" piping, plus its OEM so u cant get shit from the cops for it. the helix stuff from SubyDude is very good stuff, my friend has it on his WRX, he had a TurboXS(i think it was) cat back, but its gone now that he got pulled for it. et something that looks stock from the back!
