I have to replace a flex pipe. Any tips and tricks to getting the bolts out without breaking them? I have pb blaster and map gas.
Well that will give you an excellent start on them bolts. Make sure they glow cherry red before attempting to turn them.

Gently rotate whole clamp and grab the head with vise grips to break it loose, then use allen. Soaking with blaster of course will help

Not the clamps, the bolts that screw into the head.

Oh, sorry. Misread. For the lower bolts, I use a universal joint swivel with an impact to break them loose.

When you put those bolts back into the head are you going to use some high heat anti-seize or just put them back in? Im in the same boat as you with a broken flex pipe. Thought it was my donuts or flanges but that stuff was all mint.
