I'm wondering if that's a single in, dual out muffler....What I mean is, I think there's a chance that you have the exhaust going into the muffler in one of the pipes that it should be coming out of. ( That's unless it's not flow-directional ) Take Flowmasters for example, most of them that are single in dual out, the dual out-pipes are on the same end, and they're designed to flow 1 way. How's your gas mileage? If it's as good or better than stock, than it's not flow directional, but if you tried that with one of the dual-out 40's your gas mileage would be worse than stock....
See how they got the inlet marked on the muffler?
