np231 upgrade
Finally solved my input gear issues with my 231. Granted it was a little overkill from what I was trying to accomplish, but I am very excited about it. Can you say 4:1 tera low? Talk about an upgrade.

Got my new springs in!
I finished getting my new wagoneer springs in. I got about 1-1.5" of wheelbase out of it which I really needed for my driveline length. I did have to get these boomerang shackles made to clear the frame though. They look good and work great.

High clearance exhaust
I have had some temporary exhaust made up to be able to start it up in the shop for a while now, but I still wanted to build a complete high clearance setup to get rid of the factory manifold to O2 sensor piece. I started with a couple J bends from Summit and some extra tube as well as the mufler I bought a few months back that was on my temp exhaust.
Here is a picture of the stainless heat shield that I added to the muffler. After all, it is almost touching the floor.
Here you can see 2/3 of the exhaust after being fully welded. It looks really clean. I was able to add a flange on each side of the mufler to make it easily replaceable without having to redo the whole system.
I ended up using the stock collectors mostly because I had them, but I could've easily bought some at the muffler shop.
The tailpipe with a sweet turndown.
I routed the diver side pipe in front of the oil pan up out of the way. The passenger pipe joins in on the other side and increases to 2.5" pipe. You can see that the J bends make it very easy to route your pipes wherever you want and they make for a clean finished look. I may add some heat wrap or shielding around the oil pan if it ends up being a problem, but there is still a good ammount of space between the pipes and the pan. It will probably be fine as the factory exhaust was just as close (other than being below the pan instead of in front of it).
End result is an exhaust that sounds good, looks good, and is up and out of the way of rocks and stumps. I am very happy with how it turned out and will probably never have a custom exhaust done by a shop after experiencing how easy it is to put together and put exactly where you want it. Much cheaper too. I spent around $50 on 3 J bends, about $50 on the muffler, and another $50 or so on extra pipe and flanges. Totally custom, high clearance exhaust for $150. Hard to come anywhere close to that at a real shop.
