Ok on my truck there is a hole in the exhaust. I am not quit sure yet on where but I know its before the cat. My question is is there any way to just run dual exhaust on it I would get high flow cats for this. Will that cause any trouble codes to pop up because its different type of cat. And does any one know if I would be able to run duals at if so what size is recommended. I don't want tot just cut the cats off because that might cause some major issues later I think. If someone could enlighten me I would appreciate it thank you

Yes you can run duals with cats and o2 sensors complicated and expensive but doable billymac
