Anything that has a 2 1/2" inlet will fit, always nice to open up the outlet to something larger, that one looks nice. I've ordered some stuff from autobarn in the past, good prices, no problems.
Probably best to just bolt it on tight unless you want to weld it yourself because of $$, turn the clamp/bolt side of it up under the car so you won't see it.
