Those with kooks 2in headers, no cat midpipe
Wanting to order the 2in kooks headers and catless midpipe. For those with it Wondering if it will throw a cel which im guessing it will and wondering if this will rob any power from my car as im weary of getting a tune that will void my factory warranty. Yes i know the headers and mid pipe will void it also but i can take tose off easily if need be where is i cant hide a ecu tune from GM once they start looking at my ecu maps.
