Aftermarket Exhaust available for '08/'09 Super?

Apparently GM PN# 25808149 is discontinued which is everything post-catalytic converter. The bends and junctions are so tight I'm not sure I can recreate using off-the shelf. Anyone know of an aftermarket kit? Even if it's whatever comes after the resonator instead of the cat. My muffler seams have split. Sounds GREAT (it's an LS after all), but now the seams rattle. 😉 Waiting for the locals to hit me with a ticket.
If I have to go custom, I guess I will. Hoping for a kit and can plop in there and call it good.

You may want to check Impala SS, Monte Carlo SS, Pontiac Grand Prix GXP forums on stock or aftermarket parts as there could be something close enough to use or with very little modification.

I would go on an LS4 forum page or if you have a facebook page, search the group LS4 Nation. There's a plethora of information on anything and everything about the LS4 motors and the cars themselves.
