Not sure if i should gut my cat and put a spacer on the rear o2(anybody know if/how well this works?) or get a tune and have it deleted or just buy a new after market cat... A Borla catback is going in behind it. I'm in upstate NY and want to continue to be able to pass inspection.
This all could be avoided if theres a way to clean my old cat, its currently out of the car and clogged.
