Here's what I have on my Rex. Sounds really good - deep tone, not too loud, no rice. T304 stainless steel so it'll probably last longer than the car!
Fit's beautifully.

It came with a 4" fart can on the back that I did this with to make it look more like stock (in case you care!!)

2 1/4" i/d; 2 3/8" o/d. TheT304 is 1/16" thick. My system's 2 1/4" i/d all the way from the headers.

BTW - you're right about Autozone's prices - I wish I'd tried there before I went online!

The price was for the entire cat back, not just the muffler.

Here's the cherry bomb at $21.99
