cat delete Hi, my friend has a 2000ss z a4. He was wondering, if he were to eliminate the cats off his car, would there be any side effects ? Check engine light, ect.? How much more power could be expected?
They also sell O2 sims for the rear O2's. I had them on my car until I picked up HP Tuner and turned them off. The sim's work great. I never had the light come on with them on the car.
