Hey guys, I've been a member here for a couple of months but just recently got an 09 SS. I had a few questions on performance, from what I've read, i understand that ZZperformance is top dog with the cobalts. I just want to make sure before i start modding. Also, i dont need emissions, whats regarded as the most powerful exhaust for these cars?
We get little to no hp from exhausts, it's more about the downpipe. Recommend a 3" catless, brand is up to you. People love ZZP for the QPR (quality-to-price ratio), I went Hahn for interchangeability, others will do other things.
