are you running the exhaust into the 2 side of a 1 to2 muffler, isn't that backwards?
That exhaust is beautiful. Do you know the part number of the muffler? Jay6155
Thanks, I called the guy today, all he knows is it's a GM30, his internal part number, purchased from a warehouse by somebody else. It's made in USA. He thought maybe Walker, but their specs don't match.
Correction: 2.5" input, 2.25" exhaust. 20" long.
Good eye on the dual side/single side. Turns out the in/out are correct. Guaranteed by the different inlet/outlet sizes that I just learned about today. I found some mufflers on the flowmaster website (18", not 20") that had a similar config where the inlet and one exhaust are on the same side. It looks like this is a standard transverse application versus a front-to-back configuration.
