Hey guys, New here, but not to Mustangs. Thought I would ask for your opinions, I have a 03 Cobra and I cant seem to make up my mind about the exhaust. I am leaning towards the FRPP M-5230-M55 cat- back. Is anyone using this kit? Have any H.p. numbers?
Julio, There are in my opinion better Cat back choices then the Fr500. It is expensive ,has small tips and the only one i seen dynoed made only 11 to 12 rwhp and minimal tqe gains.
