Secondary Cat Delete Columbus Ohio
Can anyone recommend a muffler shop in the Columbus, Ohio area that's done a secondary cat delete on a 6th gen SS or ZL1?
I'm thinking about removing the secondary cats on my '17 ZL1.

Ever have any luck with this? I'm in the same boat. I've heard The Madhatter does good work but can't speak from experience.
