Ultra, you're right about the distortion. Half way through welding the Y joint it pulled quite a bit. It's because the Y joint beads are all to one side of the tube. The plan is to weld up the forward end almost completely and then break the tacks by the turbo and re-aim the last section of pipe.

Here is the slip joint. That gap is supposed to be there. It allows the pipes to grow when they get hot. It should also let the pipes move if the subframe flexes down, like from a jump. The proximity of the brake line is clearly a problem that needs to be sorted out.

Formed some tabs for the slip joint by folding some stainless around a #2 phillips screwdriver

Cut tabs to length and smooged as needed

Brazed the tabs on to minimize distortion of the slip joint. Its a really good fit. The bolt may get swapped for a shorter one with a stronger spring, if I can find one in the junk drawer.
