The new cat already had a heat shield, but it's not as large or correct as the factory shield. With some steel wool, most of the mud came off the original aluminizing, so I skipped the primer and just painted it. New tabs had to be welded onto the cat to allow the air pipe & shield to mount. It was bent from before, so it took some effort to smooth it out, and then make it clear the frame after installation. But it will protect the transmission, the cooling lines, and the (poly) radius arm bushing from the converter's heat.

I plan to replace that HEGO with a new DY-731 (F4UZ-9F472-A) when I can find one at a reasonable price.
