Awesome! And this has the ONLY set of headers PPE has made for the ISF. Were you the car they used for testing? What type of gains did they make?
Yes sir, I was the test car. It gives a 38whp gain and at 6200rpm there is a 43whp gain according to the dyno. This is with stock exhaust. so the gains will be even better with an aftermarket system.
