If you want sound and HP gains, than you need headers and that is Long Tubes friend. A simple catback will only make the car sound a a bit more aggresive and provide better exhaust flow, no noticible or no HP gains.
H-Pipe (catted or O/R) = deep rumble
X-Pipe (Catted) = raspy race car
X-Pipe (O/R) = Aggressive Raspy Race car
the best way to increase HP and BAD*** sound is to get Long Tubes with O/R xpipe. Trust me, you will love it over the H pipe. I bought the H pipe because i though raspy was too much and i ended up swithcing it out and i love it. With a proper tune, you are looking between 12 -20 HP gains with LT and O/R X pipe.
Don't waste your money, invest in a good exhaust. Kooks will be the way to go but my JBAs sound like my mustang is driven by lucifer.
