What's the secret with V-band clamps? My experience is that once installed, I break the stud when trying to get them loose again. The stainless nut seizes to the stainless stud.

I have never had an issue with V-bands. The entire exhaust system on my C6 Grand Sport Corvette has V-bands and I have had that exhaust out a couple times with out any issues, they are stainless. Is it possible someone over torqued your V-Band bolts? They dont need a whole lot of torque, snugged down is how I do them.

I have used them on several vehicles and never seen them fail or have difficulty being removed. As I mentioned above, they are literally leak proof once installed. You could apply a solid film lubricant or even ant-seize to the threads however at those temps I dont see it holding up long at all.

I come against SS fasteners all the time,
Exposed to constant heat and cool cycle SS will NOT come. apart it will galll up and break or strip.

Funny I have old ones that have been on and off many times. One stripped the rod, so I bought a new one, took it off 1 time and it was broken. I bought another one different brand same outcome.

On the thread topic, log manifold can support at least 1500 hp. guys making more with LS motors and regular exhaust manifolds.
