I have the factory exhaust system off my 94 SC in excellent condition. It was removed at approximately 28,000 miles replaced with a MN12 Performance system. I have both half’s but the front half has only two cats and a resonator per automatic 94 SC. My 95 five speed had three. The system has been stored in my garage since being removed. Not sure if it's compatible with a 4.6 but maybe.
