    Power Gains?

    Hey i was wondering what kind of power gains any of you got with a header, y-pipe, catback combination. I just got my jet hot headers and my jet hot off road y pipe that will soon be installed to connect to my Magnaflow catback exhaust. I was wondering what kinda power to the wheels any of you have encountered with similar set ups

    15-35 at the wheels.

    Depends on your tune and how it takes to the headers.

    One word of advice. Get Stainless steel band clamp, muffler tape, and sensor save high temp copper RTV.

    That's the only way I've gotten rid of leaks in my Y pipe.

    Wrap the muffler tape around each connection. Tighten the piss out of the band clamps over the muffler tape. Run the car for a week or so to heat the muffler tape properly. The use the RTV on the sides of the band clamp connections. Cover everyplace exhaust could leak out.

    It seems to be working so far.

    A nicely matched complete exhaust setup and great custom tune could easily net you 50 at the wheels over stock.

    i didnt have great traction out of the hole either.
    with slicks, i would easily be in the 11s.
    i also have a totally stock suspension.
