Hi all, I'm going to order a 3" DP & either a sports cat, or decat from Sam Bryant this weekend, just after some quick advice... Assuming I have somewhere that will pass a decat, is there any other problems associated with it? Management light,fault codes etc? I don't want a noisy car, but don't mind a little bit more grunt. Lastly, is there much of a difference between the two? Any advice ice is greatly received! Morgan.
