Yes there is...the big daddy No CEL adapters work to keep the rear o2's happy if you can keep the driver side from leaking. If you look at the bullet pipes, there is no way to get a good seal being you have a flared end from the cat back butting up to a tapered slip. All the clamp force is on the delete pipe and you can pull the cat back pipe right out of the clamp. Probably would work if you cut the flared end off the cat back and used a proper band clamp but I did not want to cut the stock exhaust or else I would just get headers... Either way I decided not to fool with it and put it back to stock. I may circle back and play around with them again at a later date. I did like the increased sound from the deletes.
