Does anybody here run long tube headers and a cat? Can you describe your setup? The LT1 in my truck does not have the AIR system so the cat would be a one in one out.
Any other thoughts or insight about this would be appriceated.
Need to insulate the pipes the cats need about 500 F going in. Read that you have shiny tubes, you're going to have to decide between shine or passing emissions. Living where I do I don't recommend ceramic coatings on the headers for a daily driver as they generally won't survive the winter.
