Don't expect much in the way of a HP gain from a simple cat-back exhaust. Gas mileage may improve, but I doubt you're going to notice a huge difference.

You might notice a small MPG gain with a cat back if you drive like a granny.

Due to all the hype and BS around all the different cat-backs I bought what was cheap, the Dynomax kit. Cheap and added a nice throaty sound..

You should check out Mudfrog's stuff in the Vendor Showcase, I built my exhaust system myself and paid more than what he's charging for an entire catback with a flowmaster, wish I would've known about him before I decided to break out the sawzall and get after it,lol.
