I'm Awesome
I need to replace a cat on my truck and was thinking of doing the whole exhaust at the same time. Headers to 3" mandrel bent tube, then to a two-into-one before the cat., a single cat, than a single 3" all the way back. My question is can I get away with using one cat versus two and not set any codes for inefficiency? I'd be welding in bungs for both downstream O2s. I have to pass emissions so deleting the last two O2's is not an option.
