 With events luckily falling into place with wheels and tires and several week nights of hanger fabrication along with well placed windows with weather, all systems were go for a Thursday morning delivery to Jecks Service Center to finally have exhaust installed. I am sure the surrounding neighbors were also happy. Transportation was supplied by my cousin, Dave Lehr who operates his own business Classic Junkyard and just happens to own a rollback. (Isn't family great?) Delivery was uneventful and after a few minute wait the CJ was driven unto the lift. After a brief description to Scott Aungst (one of the owners) of what we wanted it was left in his capable hands. Jeffrey wanted duel 2
 1/2" aluminized steel pipe to the back running through Flowmaster HP-2  mufflers and exiting with Magnaflow tips along with a threaded fitting for an O2 sensor for AFR readings to tune the carb. These mufflers were the largest/quietest that would fit into the confined space that was available. Since space was restricted, especially on the passenger side, hanger locations were fabricated and hung in the proper locations. Hangers of choice were Walker 36518 at all locations except the one used at the front of the transfercase which is an OEM style, simply made from a length of angle iron, drilled to hang from the pins and a simple 2 1/2" U clamp around the pipe. the Walker hangers were
mounted using a short section of pipe for location then drilling and tapping the crossmembers for 5/16 - 18 bolts. A mark was made on the hanger where it met the pipe then removed and bent on a simple fixture mounted to my welding table. The hanger rod was clamped, heated and bent. Scott called later in the day for us to give the OK before final welding. The slip fit joints on both ends of the mufflers were handled using Band Clamps for ease of removal for possible future Jet Hot Coating. Early Friday morning got the call that it was ready for pick up. Scott did a remarkable job with the confined available space bending the pipes, and the sound, quieter, but still had a nice throaty sound, and
those tips looked awesome protruding out the back. Just the sound and look Jeffrey was after. Now since Dave wasn't available to transport, the decision was made to drive the 8 miles of back roads home. This would be the longest trip to date. First though we traveled the mile to the local truck plaza to get this thing weighed. Curb weight for a stock CJ7 is listed around 3000 lbs. Ours came in at 3480 lbs. Trip home was tense trying to keep an eye on everything but everything worked well, nothing fell apart. The larger tires did cut down on performance slightly along with the fact that it appears to be running rich, which will be determined once the O2 sensor in installed. A stop was made at Jeffreys'
grand parents (my  parents) to show them the progress which they have not seen in quite awhile. His grandfather was and still is a source of knowledge and was helpful in several areas of this build. Altogether a product able weekend utilizing the services of committed individuals. Thanks guys.
