If you aren't cleaning the inside of that tubing before you weld it, its the grease inside from the mandrel bending process thats fouling the welds. I always weld aluminized mild steel w/o issues, but the grease will fck you everytime.
between the xpipe and the tailpipes.. the tailpipes are hard mounted at the turbo and are on hangers after they come over the axle. I plan on doing hangers for the hotside at the transmission as well. I just dont want the headers flexing or the turbosThey are used in the oem all the time so I would guess if you buy a quality piece it would fine. Where are gonna put it? Up near the header?
I like this idea, let me get the merge ect. Created first and see how much room I have left. I am using the ranger air dam under the core support, it provides a huge air pressure drop. If done correctly the engine bay should also remain cooler.They sell u bolt clamps in many different sizes at tractor supply stores and HD and Lowes. You could weld them to exhaust and bolt them to the k member with the threads pointing up. Rubber hose to insulate the top and bottom of the u bolt.
I would think a skid plate would also help air flow if it went from bottom of core support above air deflector to somewhere below rear subframe bolts. It should cause a vacuum at the rear edge at about the header flange if spaced down. It should help pull air through the radiator and out the back. High pressure in front of radiator and low pressure at the furthest edge back. Stops a bunch of air turbulence through and around engine compartment. Might be able to squeeze in a couple louvers ahead of headers as scoops and a door to access the drain plugs and filter.
I'm sleepy...almost like drinking. Smh....its been a long weekend.
