No gas smell at all. Just for comparison, the shop that installed my exhaust has an OG M2 with catless downpipes and Dinan exhaust. I just wanted to hear it when I was getting my exhaust installed. As soon as they started their M2, I could immediately smell the gas. It wasn't excessive but noticeable IMO. Mine has zero smell. I'm not worried about the inspection yet since I don't even know if I'll still have the car in 4 years
In any case, it may fail the visual inspection due to missing secondary cats.
