Well i think my Cat is shot, I can hear some hissing coming from it. Should I change it? If so what kind should I get?
I already have the flowmaster 80 series muffler 2/5 out going to 3" tail pipes.

Be sure you find out why your cat is shot. Your car may be running way too rich for it to handle. It would suck to put another cat in only to have it overheat like the first!

 

How can I tell if that the reason why?....
i can get under the car and hear a hissing sound coming from the CAT.....why would that be....a leak?
Let me ask what is a "full Cat" if I get a set of headers, a new cat, and have the flowmaster, would that make a "full cat" with out the mandrel bends?
