I know there is several threads out there about replaceing the whole system with a catback system; however, I don't have the money for that. I have decided to go with a Magnaflow after reading all the threads and seeing how everyone recomends Magnaflow over Flowmaster. I just need some help on what part number I need to do this. I have stock duals coming out the back. I am not sure what size mufler I need.
Any help would be great.
