I replaced my primaries with the high flow. Trust me, it is much deeper. My car sounded like "X" when it arrived at Fabspeed. When I picked it up with the high flow cats, X-Pipe and resonators, it was way deeper. Like "2X". Jeremy even revved it and pointed out just how much louder it was. The stock primary cats are a big restriction. Anything you remove from the stock setup will increase volume. Some things more than other things.
