Dual in single out?
Thats gunna take some serious work after the manifolds eh?

 

It shouldn't be too difficult. There is a flanged connection after each rear catalytic converter, prior to the merge on the Y-pipe. Looks simple enough to run a flanged pipe from each converter and weld the outlet of said pipe to the respective muffler inlet. Most reputable exhaust shops should be able to accomplish an install fairly easy. We offer over 15 mufflers in a number of inlet and outlet configurations so we're sure to have a replacement muffler that "fits the bill".
