I've finally got (most of) the exhaust on. I was able to get the 2-into-1 part tucked in neatly under the headers so it's down to a single 2.5" pipe as it runs back. This was a critical element in the exhaust as there is simply NO ROOM for anything else as it's verrrrrry low... truck frame sits on the ground. It's currently an open pipe behind the cab, but it will snake around some of the tube frame back-half until it gets up over the rearend on the driver's side. That's where a Flow-type muffler will go. Then it will snake back down until it gets to the center of the rear of the truck, where it'll have a handmade exhaust tip that fits up into the body. Pics when I finally get to that part.
