Don't make the mistake I did by spending 1400$ on a 3 inch cat back when you can get a nice axle back for $450-500 and save weight. If you plan on running a blower cam with a supercharger, then go with the 3 inch. Anything less than that go with an axle back.

Which cat-back was it? Corsa? I heard that one cat-back was extremely heavy but I can't remember which one it was. The OBX exhaust seemed lighter than the stock one but I didn't weigh it.
