    Yes, it should help.

    It could be a maintenance issue. Periodic replacement may be needed.

    What do you mean by "flex joint"? I would say put the flex in the hangers to account for expansion and be done with it.

    I was thinking he meant torque induced flex.

    If it were causing the pipes to contact something like the frame, that certainly would cause noise.

    In that case, rubber isolator hanger front and back, with flex pipe at the front would certainly fix the problem.

    Are you having a specific problem with the exhaust? A lot of front wheel drive cars use those braided stainless steel flex joints to allow for engine movement. I don't think I've ever seen one on a rear wheel drive car. I'm not sure what you would gain by it.

    No problems just thought it may help with little vibration in the exhaust. Just put in a new motor on the truck.

    I put stainless flex joints on my 40 just behind the v band for the header about a foot. The exhaust is very tight in areas so I was hoping it would eliminate vibrating through the hangers and it will also aid in removal and installation of the exhaust.
