My search function doesn't seem to work, anyone try these? Anyone know how they compare to X or H pipes?

 

I have the Prochamber Off-Road and Flows on my stang now and it sounds awesome. It's hard to tell when you are in the car but i have had my friends drive by me with it from low RPM to WOT and it's just MEAN. My only complaint about them, which probably goes for every after market high flow mid pipe, is the high flow sound that comes from the Headers into the mid pipe. Just a "SWOOOOOOOOSH" sound becasue all that air is flowing through compared to stock exhaust. But other then that, its awesome and i think well worth the money. Great quality and the fit was perfect.
