I recently bought a take-off 10' "S" exhaust system. My plans are to install it on my 08'. Reading through the threads it seems that most if not all the aftermarket exhaust systems tell you to get another fuel controller. Does anybody know if I'm going to have to get a fuel controller? Has anybody done the exhaust swap, if so how much extra parts are needed to complete the install. I know from sure I need new manifold bolts, different exhaust gasket, still don't know about all the hangers.
