Keep cracking/breaking flex pipe

[in2trux]

It splits/sheers from vibration. NO IMPACT! 40-50 lbs by hand, cut a longer piece of flex that fits without stress or stainless braided is better as said by others.

Then gently tighten everything up but don't make them real tight. All those pipes and exhaust components need room to stretch in the heat and flex when the frame flexes too. It sounds like someone is tightening everything up too much, possibly using impact guns instead of doing it by hand.

Just some thoughts of my own on it.

You nailed it, the damn monkey in the shop uses his impact for everything but drain plugs. I broke one wrench, then had to out a ratchet on and use my foot to even break it loose, then a wrench on the end to keep loosening it. I have a stainless flex with me now that's going on after breakfast. Thanks.
