I just installed my TBE consisting of Helix catless downpipe and Borla Single tip cat-back exhaust. i just lined up with an SRT-4 at a light and smoked him!!!! he was for sure racing cuz he chirped his tires and he was revving his engine. My setup sounds SICK, I can now hear my turbo spool up. Next is COBB AP then MBC, then it's VF34 and supporting mods unless you people can recommend a better turbo.
