Kolak exhaust - rattling and banging around

Got my Kolak exhaust system a while ago. Love it. Except for one thing,
Its a tight space where the exhaust pipe hops over the rear axle, and on bumpy gravel roads (I'm on a lot of them) That thing bangs and thumps into the axle and the body. Rattling is making me more nuts than normal.
There is a hanger right near that location, with a rubber grommet that supports the system and it looks to be in OK shape.
I'm looking for ideas for better support that won't increase the normal drone from a louder exhaust.
Any ideas?
Anybody else had the problem?
Thanks in advance!

Have you tried adjusting the tailpipe hanger to move the tailpipe laterally for better clearance? Maybe a little lateral adjustment will allow for better clearance.

Ive found bending it with a pipe wrench works well to add a little movement away from other parts. It also adds some tension to keep it off other parts.


Of all the things Ive lost
The one I miss most is my mind

Its like a fart in a windstorm
It smells good but thats about it

Mine was rattling also after a recent new tailpipe install. It wasn't vertical. I loosened the clamp and rotated the pipe and now no more rattle.
