Just wondering if anyone with a supercharger has one. If so what are your thoughts and how does the pipe hookup with the cat. Do you need a 3 inch cat as well??

 

I used to have that setup but use a test pipe now instead, but yes you need a 3" cat too, i used one from Random Technologies, i think now Warp speed sells the carsound 3" cats too, not sure, its pretty nice though, just bolts right onto the cat and then whatever is after your car slips on too
