I have a 4.7L 2002 Ram. I will be getting a complete Flowmaster exhaust soon. I am VERY interested in this electric cutout I have been reading about lately. I have gone to Quicktimeperformance.com and looked at the various models. Anyone knoe the difference between the sizes? I am assuming you need to get a size to match your exhaust pipes. Any recommendations? Also, do you think if I but the cutout before I get the exhaust put on, that the shop will install it for me at the time they put my Flowmaster on?
