i need an exhaust with a built on cat that doesnt need an air pump that bolts on a set of headers

 

Custom is the cheapest way to do it. I think I spent about 100 bucks on mine, but I dont have a cat at all.

 

go to a farm and fleet or anyplace that sells universal cats. not autozone or anything like that cause there out of line with the prices, but im talkin about maybe a farm tracter suply or farm n fleet or fleet farm or something like them. buy a 3 stage v8 universal cat in the size piping that you want with no air tube and then take it to a muffler shop and have them weld it in.

 

Custom is a cheap way to go. Just have a good welder do it for you. Buying this **** at the store= 2-3 mths. of insurance coverage
