Hello All, Just curious if anyone has had experience with the Hyperflow Cats for the Challenge Stradale? I have "high" flow D) pipes and I'm really sick of the damned CEL that keeps coming on. There seems to be no fix as far as the OBD II error codes are concerned since that's what the technicians at a couple of the dealerships have told me. Putting the stock cats is out of the question since the oh-so beautiful sound of the car would be lost. Therefore, it was suggested that I give the Hyperflow Cats a try. Also, where is the best place to get these Hyperflow Cats for the Stradale? Any help on this is appreciated.
