So I finally got my new studs in with the nuts safety wired and rode the bike. The studs held up well but the lower mounts did not. The clamp mount to the Y-mount lost the rubber/silicone gasket. The rear most mount broke the mount. NOT the mount on the muffler but the piece that goes between there and the frame. Any suggestions on how to get this taken care of once and for all?

I have a 2"wide stainless band clamp from an auto parts store in front and a standard exhaust hanger in back with rubber washers on both sides of it where it bolts to the engine cases. I have not had any problems with this since installing it about 4K miles ago. My Force pipe came from another Bad Webber and had the old style bracket in front that always cracked.

the weird thing is that it hangs about 1/2 inch lower than the front mounting bracket. I assume this is because of the silicone/rubber that is supposed to be there but I don't know if the bracket should/could be moved down or not

I made a strap out of a piece of 1/8" flat stock and used the exhaust studs and rear hanger to align, then tightened the front strap last

are you using any rubber or silicone on the front strap? Mine is gone and I don't know if there is an OEM part to replace it. I know I can spend 30 bucks and get it from force but I will be really angry if I spend it and lose the gasket/dampner again

I have the clamp directly around the pipe with no silicone insert. I figure that due to the increased surface area of the clamp that the silicone is not necessary.The Jet hot ceramic coating is hard and if the pipe is not moving around in the clamp, I figure that it should be OK. My impression is that the silicone is to protect the finish on the pipe but I can't substantiate that. I haven't seen any evidence of the pipe moving around and the couple times the back hanger was getting loose, I felt it in the pegs immediately.

while we are on the force subject......my rear hanger has never been attatched to the bottom of the motor, the holes in the hanger and the mounting hole do not line up, it can be forced into place if i had a bolt, but it doesnt rattle or move around at all......do i need to bolt it, or should i use a piece of rubber like an aftermarket car hanger and bolt the top to the motor and the other end of the rubber to the force hole? my header shows no signs of cracking

Auto parts store strap with rubber on the bottom. Tighten up the studs first and then the other mounts so that nothing is pulling the pipe out of alignment and you should be OK.

The rear mount is there for a reason. You would be well served to use all the attachment points that were built onto the pipe. The stock pipe attaches under the motor to provide needed support and to keep vibration from damaging mounts upstream

Sure. Not real pretty but functional. I really should clean this up as I have put so much into details elsewhere. This pic is a little embarising but it has been working for over 4K miles so far. I take a general look see every week and no signs of fatigue. I'm surprised that you don't have an incredible amount of vibration running without the back mount attached.
