i ordered the oval one as the 2nd muffler, i had the same problem, i took it to the wonderful muffler man on rice and one of the techs used there exhaust pipe expander and opened it up, make sure to test fit it before you leave, its easy to do, it took the guy 3 tries to get it right and it only cost me $5 cash.
I just noticed that i didn't tighten down one of the bolts on the flange underneath the car, make sure to get those nice and tight while its cool to the touch.
And yes the car will smell like that, un-catalyzed exhaust smells funky. I also got a W.B. bung in mine but i don't really like where its placed.
