So I'm about to order a muffler for my exhaust, but I've run into a bit of a conundrum. I'm looking for an exhaust with with a single inlet and duel outlet, similar to that of the GT-R. Magnaflow makes a muffler here that appears to already have the 180 degree bent pipe, which will make my life a lot easier. Only problem is, I need that to be an inlet, but it says its an outlet. The other magnaflow muffler I was looking at here is single in, duel out (reversable) but doesn't have the 180 degree bend. So after all this rambling, my question is, does anyone know if I can use the first muffler's inlet as an outlet, or is there another muffler similar in style, but functions as I need it to, that I can get.
