well I ended up spending a bunch of time doing maintenance on this thing, which is boring AF so haven't been updating much.
-Changed oil in trans, tcase, front diff, rear diff
-fixed front diff breather, as the fitting had broken and let water into the front diff oil
-new fuel injectors and FPR
-new exhaust gasket from left bank to y-pipe
-added rear coil spring spacers (has OME 919 springs in it already) to make up for the extra weight I've added, went ahead and fit some Nissan frontier nitro shocks which are about 2" longer extended, an only about 1" longer compressed. also made a bracket to space up the rear brake line Tee so that the brake line won't stretch, as well as extended the rear diff breather.
and after all that I realized the exhaust system needed to be changed as the cat was clogging up after it got hot, and it would start to cut out under high throttle input, and the rest of it was rusting out.
so I decided to get all budget racecar with it, since that's the only way I know how to make exhaust systems.
ugly welds, don't care. it works. also retains all the factory hangers which I'm pretty excited about, and I can't tell any difference in volume when cruising on the highway, which is great. around town with the windows down is slightly louder, but not bad.
the truck runs really good now too, though I probably lost a little low end torque from the bigger exhaust. and after all the maintenance it no longer has a weird shudder at 55mph, which I thought before was just wind noise.
