Thanks guys.
Beertestr, I initially wanted to try to use a NBS exhaust. They yard where I was digging didn't have any in good shape. It's nice to know that they will work though. I'm planning on doing this again in a lowered 2wd obs.
Now that I think about it, I'm pretty sure we put away a few 12 packs of Yuenglings during the frame rehab. haha
jcrumpley, I don't have any pics from above. I'll try to get you one at some point, after I get back up to my cabin. I used a 90 degree 4" to 3.5" reducing coupler for the intake. The tubing is 3.5" with a 45 degree bend. I just cut it to fit. It's pretty close to the upper rad hose, but it works great.
