Those DH owners with Ford Performance SC Weigh in

[Q6543]

I don’t have a check engine light, I used autozone spark defoulers
And no, we don’t have any emissions testing in Mi.

if we did I’d be driving a Tesla plaid by next week.

Thanks everyone for input. I’m only daily driving mine and don’t plan to do any racing. I believe if Ford needed cats to be replaced or removed they would have required it. I’ve had GT500s and daily driving them I rarely got into heavy boost. Again I appreciate all the input. I’ve ordered my kit and it will be installed at a local dealership that I trust.

You could buy cats for this level of power that would live, but, you'll lose some hp and noise, and they are expensive AF.

I doubt you would lose any horsepower. Some of those cats have 4" inlets and outlets. They are made for flow in addition to being made to live with extremely high horsepower.
