AAM Competition S-Line Short Tail Axle-Back Exhaust

I don't see how it can negatively impact power over the stock muffler. The level of restriction in the exhaust goes like this in my opinion (1 being the most):

1) Stock catalytic converters
2) Stock Y pipe
3) Stock muffler

I am sure these will provide decent gains since they are eliminating a pretty convoluted stock muffler design.
