    I went to a Flowmaster II cat back system. It will give you a 10% jump in HP. Good luck. /forums/images/graemlins/k5.gif /forums/images/graemlins/usaflag.gif /forums/images/graemlins/thumb.gif

    you will probably hear your performance "gain" more than actually feel it...

    I agree with the Fedneck. Any small gain you experience through just a muffler change is probably imagined. Most butt dynos cannot feel an additional 2-5# of tq
