I know this is a Dodge Site and i drive a Dodge Ram 3500 myself :) My friend has a 2000 GMC Sierra 1500. The exhaust is out problem, he has headers and Magnaflow exhaust. The Y pipe and the cats are our problem. Their are O2 Sensors before and after the cats. I was wondering if we could cut the cats out and weld in pipe the same diameter of the rest of the exhaust and not have problems, with trouble codes and such, or do we need to get high flow cats?
