Muffler Problem??
Just picked up a '92 with 3.9 V6 and AT. This thing is getting horrible mileage (12-15mpg at best). The exhaust was new when I bought it and has been a little on the loud side (compared to my '94 4x4 with same motor/tranny combo) but at the same time it sounds a little restricted. I crawled under to take a look and I noticed the muffler has arrows pointing in both directions with a 4 on the input side of the arrow and an 8 on the output side. Anyone have any ideas on whether there is an issue here?
Thanks!

I think its just a reversible muffler for various applications. Like the Thrush Turbos, Welded, etc. I think theyre an A and B, not 4 and 8, just to symbolise which inlet/outlet is which. I'm assuming the A pipe is closer to the inside of the truck and the B pipe is towards the outside, offset from each other, right?
