Picked up a new Miat. I am unfortunately in an emissions county in Texas. The car has the Roadster Sport Header and I am popping a P0421. Anyone have a solution from experience that doesn’t involve spending $1000?

Trying to judge interest before I go through development on a mold for this flush fit rear bumper. Will start with what you see here as a base and be altered slightly for improvement in fit. No exhaust cut outs. I would probably need to sell 10~ to get it to be worth it. Just don’t want to make something no one wants.
