I Need a Cat

Well, I just bought myself the Magnaflow 16829 3" Catback and Hedman 68481 Headers. I'm just wondering what cat I should go with? I know the Magnaflow 93441 will slip onto the catback side, but I have no clue if it will fit the y-pipe side. Any help will be much appreciated.

Shawn

Magnaflow.

Random Technology and Catco are fine too.

Thanks for the response, but how do these hook up to the y-pipe that is 2 1/2"? The 93441 is 3" on both sides.

Alright here. With these reducers, should they slip over the y-pipe and go into the cat, or is it the other way around? And how would it stay in place, shouldn't I need a some type of clamp? I have no previous knowledge of exhaust, thats why I sound like an idiot.

Re: I Need a Cat

From what I hear, anything from CarSound (Magnaflow), Random Technology, and Catco, are all good cats. I just picked me up a Magnaflow 93441 cat to match my Magnaflow 16829 catback.
