Got to cut the stock pipe to take it off. This is where we cut it.

Thats nice to hear,I did'nt think that exhaust would put down that kind of power because of
it's 2 1/4 size.What was the temp. difference between your stock run and your gmpp exhaust.

I agree.
The 2 dyno's are a week apart and at different times of the day.
Was it hot during the first session?
But like you said, good gains.

Nice gains, though! Exhaust will likely be one of my last mods, if not the last, but this will help me have my decision made when the time comes!
