I couldn't imagine what it would sound like with test pipes. The HFC's and catback sounds insane. Getting even better as it breaks in. Only gripe is that I wish they offered carbon fiber tips as an option. The ones that come with the exhaust could be better aesthetically.

I can't wait to hear how it would sounds paired with the Concept 841 headers. The 841 is epic.

There are no guarantees with any high flow cats, but I can report I have over 4000 miles with no cel ever. Same for a friend that had his installed a month apart. Both cars 2024 models with Milltek 200 core high flow cats.

I have Miltek high flow cats and had to use the mini cats to get past the clearance issues with the eVenturi air intake. Alas it did not solve my CEL issues either. I had to use 45 degree ones to get the clearance, but maybe the big daddy ones will fit, but I don’t think it would solve it. I got a lot of miles before the first CEL, and it will throw them quickly on track. So I just got a CELsync and left it at that. Tune will be next.
