Stupid question about cats

Hey, i know this will probably sound like a stupid question, but what exactly are "cats". Does this term refer to the catback exhaust, or is it something totally different? Thanks

Changeing the cat-back will, not the catalytic converters.

If you go to a Z06 system, you will be eliminating 2 of the 4 cats your car has. The Z doesnt use the "pup cats" as do the other models......so yes, using a sytem from a Z will change your exhaust tone , beit only slightly, but whats better than that is the better flow you will achieve. I would ditch the whole idea though & go with a quality set of longtube headders, an X pipe & a pair of high flow cats..

Changing just your cats will not help your sound. Changing to headers and/or changing the cat-back (mufflers) will.

Do a search for header install (probably by England Green) and you will get a bunch of photos to refer to. The pipe with the "bulge" in it will be the hi-flow cats. The 6ft long section they are in is commonly referred to as the mid-pipe (and almost always includes an x-pipe). The pipe that goes over the rear axles and includes the mufflers and tips is called the cat-back.
