I'd talk to a couple local exhaust shops before you decide to drop the cash on a catback. You'll open up a whole lot more options that way. Listen to some youtube videos to get an idea of the sound your looking for, and have your local shop build you a system YOU want. I got a true dual system with magnaflows, all stainless including new hangers and a lifetime warranty for $220, that's including the magnaflows as well. I couldn't have bought the materials and done the work myself for that let alone buy a catback. The guy does amazing work and stands by his warranties 100%. I don't see myself ever buying an off the shelf catback again. You're best bet is to find an independent shop or one that strictly specializes in exhaust work. If you go to a Midas, Monroe ect. most of the time they will tell you its impossible to install anything but their piece of crap replacement system for $1000.
