I'm picking up my new 2012 Ram 2500HD crew cab 4x4 tomorrow. This truck has the 5.7L Hemi in it. I'm planning to do a few things to this truck. Question. Will running a cats-back dual exhaust have any negative effects on this truck?
I was told by a sales manager (who places the actual orders) that the 1500s have it as option because of the back pressure being reduced with a lot of aftermarket stuff. Yet they don't offer it as an option for the 2500+ trucks. Kind of weird. As long as you're behind the CAT I don't think you can mess your warranty up and it should give you a little bump in fuel economy, unless as previously mentioned you like the sound TOO MUCH haha. When mine arrives from the factory the dealer will be putting a cat back on before I even pick her up.
