These are the before and after on the full exhaust. all mac including longtubes, o/r h pipe and cat back. Im not sure if I am impressed or not, but i guess it is ok for a bone stock motor.

So you are not happy with 25hp and 30tq? Looking at the two days the temps were really close and actually a bit warmer on 4-2-09. Had you done the test on the same day you may have even made a couple more ponies.

Nice numbers.

Well I suppose the gains are really good. All of it combined cost me 300.
120 for headers and h pipe and 180 for the cat back. Still curious with the motor being stock how much more power I would have got out of shortys?
