Don't just buy a muffler, go for a complete cat-back.
Yeah it's more expensive, but it is definately worth every dime.
I got the same muffler as redhawk (12" Oval body 4X7 magnaflow aluminized).
No resonantor for me though, just 2.25" piping back to my muffler.
After getting a new exhaust, make sure you "fix" the pre cat. (Mystery Mod)

I put the round body in to control the sound. The straight-pipe exhausts I have heard can drone at hwy speeds and also have a fair amoutn of rasp.
My exhaust is much more understated than that.
Since it has a center diameter of 3", the flow is not disrupted but sounds more refined than a straight pipe.
The sound, of course, is an opinion. I don't like the sound of resonatorless exhausts, but that's just me...
