If you guys seem the inside of the stock ones you would be saying the samething. There so shi**y and way to restrictive looking inside of the stocks. IDK it just doesnt make sense.

RE: No hp from aftermarket axle backs!
i just like the sound better with a straight through snuffler. i have had other cars that you could feel the difference with an exhaust upgrade. i think ford did a good job designing ours for max performance in a basically stock format. i definitly wouldnt run a stock exhaust though if i was pushin better than 400hp.

This is the only back to back test I've seen... its on a GT500 so maybe we get 1/2??

Why would they only measure up to 4k RPM, and why would their run start 500 RPM later than the baseline??
Complete BS.

Just adding a straight through style axleback will add no power. A stock 3 valve motor needs some back pressure anyways. It is not like you are pushing massive air through the intake that you need to open up the exhaust to accomodate it. Stock engines run best with proper backpressure.

I know, its just a typo, and I'm not being a jerk,but when I read it the first time it made me LOL.

Don't expect any noticeable power increase from any cat back/axle back alone. It just doesn't happen. I bought my Corsa for sound quality. Because it's a blown motor I may gain a little power, but I ain't counting on it.
