I agree that its not enough to feel in the seat of the pants, but why wouldn't it make additional horsepower over the regular exhaust? I suspect that Chevy isn't claiming it because they haven't gotten around to certifying it.

I'll be interested to see what happens when somone puts an NPP on a dyno.
