Rubber Mounted Engine Exhaust Hanger
So got me a new FXSTS and got to messing with the pipes. Noticed that the exhaust has a solid mount for the rear of the pipes that mounts to the frame. But the engine is moving and flexing and naturally vibrates when riding. Was wondering if maybe adding some rubber washers between the mount and the frame may relieve some of the stress, or am I overthinking things here. Pipes are freedom performance declaration turnouts. Pipes that came with bike were straight pipes and were mounted with billet bushings so no change in vibration.

I'm with Multi. It didn't come with a rubber mount exhaust hanger and the engine is solid mounted. I would think that adding anything that would allow flex could introduce enough vibration/movement to wind up with a crack or at least a leak somewhere up the line. That said, I can't spell "engineer" without spell check.
