Hey I was just wondering what all it would take to put a dual cat catback on a single cat car?

 

No one huh I quess it could just be taken to a good exhaust shop and have it fabbed on!

 

Yep, not too hard, especially if you use the small high flow cats. If you have headers you'll need a new Y-pipe (and probably even if you don't have headers)....

 

what I mean is, on my car right not I have a flowmaster catback, and my car has dual cats. I am going to be getting a new catback and Im looking to sell this one. Someone is interested, but they have an 86 trans am with a single cat exhaust, what does it take to get my dual cat catback to fit on a car with a single cat?

 

They'll have to get a new Y-pipe (or use yours if you're converting to a single cat and you can get it off w/o destroying it) at a minimum.

What exactly are you getting new? It all depends on your definition of a "cat back". Officially (I think), a "cat back" on our 3rd gens is the flared large single pipe that goes back over the axle to the muffler and the out the muffler to the bumper. Is that all you're getting, or does your replacement parts start at the front (or back?) of the cats?

Where your replacement parts "start" will control what the other guy needs.

If you're staying with a dual cat setup (which is the best performance in my opinion), and just getting the large single pipe on back thru the muffler to the bumper, the other guy won't need anything else cause he'll just be switching his current large pipe and muffler set up for yours (meaning he'll still be running a single cat).

If your getting the everything from the front of the cats on back as replacement parts, he'll need everything you take off plus a new Y-pipe for dual cats.

Does any of that make sense? Not too sure I was very clear on this.....
