High Flow Cats

Anyone in NY with a C7 or C8 have high flow cats? If so, do you have any issues passing inspection? I’m considering 2M HFC but not sure if I’ll run into inspection issues with NY law.

I have a 25’ ZO6. The sound of the car is intoxicating. I actually thought (for 1 second) about High Flow Cats. THEN…..I woke up and started reading numerous threads about check engine lights and bad high priced products (SOUL).
After a brief thought, no way. If you have a Stingray and you want sound. Get a ZO6 IMHO. You are chasing something the Stingray is not designed to give you. Dumping money in a car you will never get back.

I am actually considering a Z06 but may not pull the trigger until next year. I truly do love my Stingray, I just wish it was a tad bit more louder. With the roof off, once all the pipes are warmed up, and in Z mode with engine noise up and exhaust flaps open, it sounds pretty good. But the issue is the sound goes away unless you’re in manual mode and keep RPMs higher.
