Just an FYI....there's already a true-dual exhaust for sale. Cardoc has it for sale...it's 350$ for the Aluminized version and 500$ for the Stainless steel version. It's basically straight back from the exhaust manifolds, goes into the cats, and into (I believe) a flowmaster or some sort of muffler with 2-in-2-out configuration. I can get you more info if you want-E-mail me directly at carcrzy2k@worldnet.att.net
