The only kit is from GM and its $800 for the stock piece. However you can get dual-cat headers and a y-pipe, or you pay a muffler shop to make up a custom y-pipe for you. I dont know of an aftermarket dual-cat y-pipe that bolts up the stock manifolds.

Why do you want them that badly? Just get a set of headers and a high flow 3" cat. You're looking at the same price range and the header/high flow single cat will kick the crap outta the stock manifold/dual cat setup performance wise...
