mine is back touching the plastic or ruber insolation on back firewall has not even warp it because of the heat shield on the exhaust also use tri-flow or something to losen i use 15mm wrench and tap it with hammer to break them losse then i used 1/2 wrench with hammer to take bolts out of turbo then gently tap hot side back and forth with a hammer and it came apart

kieth, the non-ic pipe does not have the heat shield.

I think the best way to do that would be to take about a one inch slice out of it a couple inches behind the turbo flange and weld it back up.

who else has done this? yes.. no heat shield.

I just cut a little of the insulation off the heater box to make sure it cleared. Worked/s fine. I would second the best route to be slicing and rewelding though. But whatever works! It's not a necessity. Luckily my 4" still clears it

Or you could make a heat shield and and weld her up to be extra safe
