need some help with a question that is pretty dumb but i still need to ask it. i wanna run a dual magnaflow set up from the cats back on my 01, however my engine size is a gutless 4.2. the only set up i could find fitting what i want is a gibson but the site said it wasnt stainless and i live in canada so anything other is a waste of money. my question is two parts; does anyone know of a kit by magnaflow for a 4.2 or could i get away with using the setup built for the 4.6.... any help would be appreciated...thanks
