Should have gotten a down pipe back exhaust that would have helped also. Loose the kitty cat
i never got a check engine light on mine....I think you have talked me into it. Ive debated it bc of emission laws/check engine light, but I think I can clear any possible codes with my tuner and I also believe that I may be exempt from standard emissions testing. I was talking with worker from dept. motor veh and he stated that diesel pickups registered over 8500 lbs and less then 10000 are not subject to emission tests, but a cat is still required if it came stock on the truck. So maybe I will take my chances
Good maybe it wont even be an issue theni never got a check engine light on mine....
