I have Dynomax resonators and Magnaflow mufflers.
I bought the tiny rear Magnaflows because they easily fit in the stock location.
If I did it again I would just stuff (and I mean stuff

) the normal size Ultraflows there.
I had Ultraflows on the F-body setup and it was the best sounding Contour exhaust I have ever heard. Very throaty, exotic, sporty sounding.
I agree the Magnaflows are a bit "boomy" for my taste. However they do sound really cool at idle.
Dynomax sells those import style mufflers btw. I don't know about the variety but they do make some.
