Here is the original thread with all the trials and tribulations. http://www.forabodiesonly.com/mopar/showthread.php?t=174333 It really wasn't that bad. We made our own exhaust without a pipe bender, and that took time. The buddy who was helping me and doing the bulk of the work is crew chief on a race team. You can't buy anything for those cars and have to make everything. That came in handy here because everything was manufactured by hand. It was fun but time consuming. In the end, all I can say is, holy ****, this thing is fast!
