Are going to just have your Y-pipe modded or are you going to get the factory dual pipe from a 6.0?

 

Since the corsa comes with a y-pipe in front of the muffler, I am going to use that y-pipe and just run the rest to each bank.

Hopefully, I will have it on by next weekend then to the muffler shop connect the pieces.

 

Post some pictures when you get it done!!!

 

Since its dual to the muffler you can just get the intermediate pipes from the HD and a new manifold. One of the manifolds on the HD is different but I forget which one; I think its the driver side.

 

I plan on headers later so I'll just rig it up for right now to work...the Corsa has an extended y-pipe to attach the pipes.

 

Ok..just an update...the hangers in front and behind the muffler work fine and fit fine. However, I'm going to run a 3" pipe from the factory y-pipe to the Corsa muffler and not use the dual 3" to single 3" stainless steel y-pipe that comes with it. So, that might be up for sale here shortly...looks very nice but a stock 5.3L doesn't need 3"....2.5" would be fine. The rest of the system needs some custom hanger work but that's about it.
