Good evening all, I have a 2k C3500 cab and chassis RCSB. I am looking to shorten the factory exhaust system while maintaining the OEM muffler. I would like it to have a side exit with a turndown immediately behind the cab. What I am unsure of is what exactly I'd have to do to keep all my O2 sensors and fool the system into thinking all is normal. Haven't learned much about this stuff yet so any info or advice would be much appreciated
