I was reading through magnaflow's site but couldn't quite find the info I needed.

Do they offer a direct fit bolt in cat for civics that's 2.25" so you can just bolt it in between and DC header and a WS2 exhaust?

Or do you have to get a universal and make your own flanges?

 

You could get a universal and cut out the test pipe and weld it in it's place. That worked great for me.

 

What does the test pipe come with? Does it come with the header or the cat back?

 

It's the part of the header the company will call a "cat".
