I have a custom made CAT-BACK exhaust from FLOWMASTER. (or is it cat back ;-) )
It was designed and built by Flowmaster at their R&D facility in Santa Rosa California.
This is a 1 of a kind exhaust. It also has a "fake" CAT feature as well. The CAT it comes with removable (bolts in) and allows you to run a real CAT for the smog patrol.. The CAT included is just for looks, it serves no function.
It has a great sound to it.
$250 + shipping gets you all the parts.
If I can locate them, I also have a 2nd set of tips for the exhaust. They are resonators and look menacing, and cut the sound down, but look darth vader like.
If I can find the other exhaust tips, I will throw them in for free.
