Guys i need your help!!!
I want to buy an exhaust system for my 2013 z and I don't know whether I should get the FAST INTENTIONS exhaust system or a BORLA system...I want the car to have a deeper more intense roar and I don't know which one is better for me...and also I'm looking to most likely put on some stillen HFC's if that makes any difference to your answer. Please help!
