I made a custom exhaust using magnaflows. Pics can be found here:

It's 10lbs as it sits. It uses 2 x 642-14414 Magnaflow mufflers, 2" piping and 3" rolled, polished tips. It bolts on easily and looks fantastic on the car. If you're at all interested, shoot me an e-mail. vitamvauser at hotmail dot com.
