If you put two mufflers back there, thatll be even more to hang down underneath your bumper and look bad (personal opinion)...I was following a 00+ SE this morning and couldnt help but notice that the stock muffler hangs down a lot and looks really tacky.
If you could use one muffler in a different, more concealable location and then run pipes to each side of the bumper and have dual-tips, I think that would look decent. Because I really dont think the SE'* have enough of a rear bumper to hide 1 muffler, let alone 2.
Ive never seen the exhaust on your car though, so I dont know if its feasible, but a single in/ dual out muffler might be the ticket.
