I am trying to get a good muffler on my new SD and eliminate the resonator and want to make sure of a couple of things: first, if I am correct the inlet to the resonator is 2.5", the outlet/muffler inlet is 3", and the muffler outlet is 3.5". I have found a Magnaflow y-pipe with a 2.5" inlet and 3" outlet and a 3" to 3.5" adapter. If these dimensions are correct then I think I am in business.

 

Sorry I posted this question in the 6.2 forum. If someone knows how to delete this one please let me know.
