I have stainless steel headers and h-pipe with no catalytic converters. It's inspection time and I want to pass with no problems. I want to put the catalytic converters after the h-pipe because I will be getting rid of it for a turbo system. I also think it will be much easier to install in the steel pipe rather that cutting up my h-pipe which I will be selling for the turbo. I've not seen this done yet and was wondering if it sounds like a good idea?
