This is definitly false and what about the borla catless down pipe. Also look to the hooker catback system in this same forum that adds about 20 hp

Ok, cat-back and even axle-back will increase power on these cars because of the massive restriction the stock system has in place.

As for saying cat-backs don't increase power on modern cars that's wrong 100% if he said axle-backs he'd be correct on alot of modern cars.
