After fixing leak at the pipe and manifold (left bank) and replacing ALL O2 sensors that cat code came up. Any fixes other than replacing Cat?
Probably not. IF emissions testing is done where you're at , you might seriously consider factory converter , as I've seen many aftermarket converters that aren't up to par with OEM converters. Just a thought.
