pm me...BSR is meh in the C30 ..also borla is coming out with a CBE that sounds like sex

Woulda waited on the tune for an IPD tune, but BSR makes a pretty good product

The AM CAI's for the c30 are kinda pointless.....(like the evolve/K&N thing i have on my car....just makes turbo louder hahahah)

lol here ima save myself some typing time....C30world.com (ATL_cruisin is my name, got to the performance section if u have any questions)

oh to answer the HP question ATP said 350 ish outa the stock motor is easy sauce....400 u might blow it
