I was wondering if anyone has run up against any incompatibilities between aftermarket exhausts and receiver hitches. I've got a Draw-tite on my wagon, and the stock exhaust. I was thinking about a cat-back, but it looks like there's no way a melon-shooter will fit (not that that was my preference).

Anyone try any of the other single or double tip styles?

I don't know what your Draw-tite hitch looks like, but if it looks similar to my Da'lan hitch, then your best bet is the Stromung dual-tip exhaust. Mine is a cat-back with 2.5" piping. The dual tips extend from the bottom of the muffler, as in the stock exhaust, giving it more room for the hitch to go "over" it than any another aftermarket exhaust I've seen. It doesn't hurt that the Stromung is very well-built with a nice, but not too loud, sound.

You can see more pictures of the exhaust and the hitch in my webpage:

I run the Prodrive WR Sport Axle back exhaust with the subaru hitch and it fits fine plenty of room. This is a single tip oval.
