Do some youtube searching......most all of the available options are there for you to see.

Personally, I like the 16633 Magnaflow cat-back, so that's what I installed.


As a sidenote....if you're going with an entire cat-back system, be forewarned, you have to remove the underbody brace on the Roadster. When I did mine, I just removed the 4 bolts at the back and let it drop down a little, I had just enough clearance to get the old stuff out and the new in.

If you decide on nothing but the muffler you shouldn't have to mess with the brace.
