Default can't wait to seethe results.

I have heard that the stock side pipes cut at least 100 hp. I am still waiting to dyno my car to see once the new motor is broken in. My engine builder estimates that it should be about 650 both ways at the crank. If it was actually a little quieter, that would be a bonus. I actually feel sorry for my neighbors who other wise like the fact that I have loud cars up at my house.
