Hi Audrey, yes I do exhaust systems. I also have just finished my system. 2.5" twin stainless from extractors with 'x' pipe, expansion chambers & magnaflow mufflers. (351windsor) The supply agent is local (Osborne Park) They are one of my major exhaust suppliers for magnaflow. Has to be custom made. But that is what I do. My front suspension is modified slightly to Shelby specs (minor mod)
