[UPDATE--1/23/07)--I've custom fabbed an exhaust system. I ordered some mandrel bent angle pieces that I will cut and weld together to go over and around the transfer case.
There's the tubing! That ought to flow-it's 3" Lookin for a band saw to cut tubing with, it's the only way to get a clean and accurate enough cut.
There some pics of why I need to change this exhaust system. As you can see the previous owner simply smashed the pipe in about halfway to barely clear the transfer case.
(looking down the inside of the tube)
This being right behind the header outlet will kill horsepower big time. It also left the outlet rubbing right against the shock boot! There was no attempt at securing the end of the pipe with a hanger. The driver's side was left sitting on top of the rear axle! As the axle moved the exhaust system had to move with it-obviously this wasn't going to work either. I've made some adjustments to the driver's side already, a simple angle cut and weld and a new hanger and we are good to go. (UPDATE 3/16/07)--Got a bandsaw-it looks like it works awesome!
It can either work vertical or horizontal-it has a gravity feed feature where you can clamp down the piece to be cut and turn on the saw and walk away.
It will shut itself off after the cut is complete. Pretty nice for $200 from Harbor Freight. It will give me the straight and clean cut that I need to do the exhaust tubing and weld back together cleanly. I didnt have a good way to do this before- hacksaws and cut-off wheels on angle grinders don't cut it clean and accurate enough. Not to mention the amount of work it is to manually cut this stuff - really takes a long time too. Obviously I'm stoked about my new tool!
(update-it's now 4/22/07) There's the new passenger side exhaust, first one showing some of the process of welding together and cutting off the excess. Second one is the finished product. You wind up with a 3" mandrel bent exhaust piece that nobody sells. The alternative is easier of course, simply go to an exhaust shop and have them do it. The results though won't be anywhere near as nice- both in flow and appearance. If I wanted to be really trick I would grind off the welds so that it all appears as one tube.
However when the skid plate is installed (see picture)you really don't see any of the exhaust -so it would be kind of a waste of time. But.....
--Stay tuned for further developments!
Note the brake hose is relocated to the top of the axle pumpkin. Stock it is off to one side on the passenger axle tube. My modification will allow the axle to flex more without fear of over extending the hose.
That's the driver's side shown without the skidplate in place. I had to redo the mounting for the skid plate as the bolt's threaded inserts in the frame are wasted. I'm drilling holes in the frame so I can access the inside of the fully boxed rails-once done I will use grade 8 nuts on top of the new grade 8 bolts.(update- it's done-you can see the holes in the frame in the above close-up of the skidplate.) Anyone that has dropped one of thse skidplates before can imagine what that means when the bolts are stripped out - PITA! Hopefully this will mean the end of that trouble and the skidplate will be accessible easily even when off-road. Before that skidplate got installed I put on a new polyurathane transmission mount, the stock one was toast and was missing a bolt because of stripped threads. That wouldn't have worked very long off road. That's not photoshop-it's really that red!
