As of right now I'm just buying a new muffler, basically my stock one on the black part just inside the steel tip has a few rust spots on it, as well as an annoying rattle that my muffler has had ever since I've had it.

But basically I'm looking at Magnaflows, but wondering what I need to look for when looking at mufflers, anything in particular? I'm wanting one that has an angle cut and looks good under the stock rear bumper of the 2000.

Some of my questions are will round ones work? Are they better or worse, and is double wall better or worse and what is double wall exactly, etc...?

Thanks guys...
