will ORY vibration through rubber hanger cause KR? Well after my poly driver's mount was broken in the y-pipe banging started happening again. This time I wedged a 1/4" thick exhaust hanger (rubber material) between the y and the car and bolted it in place using an existing bolt for a heat shield. The other end of the piece of rubber is ziptied to the subframe connector. So basically the ORY is in constant contact with this piece of rubber which is in constant contact w/ the underside of the car. I've noticed more vibration after doing this (since the y is always touching the rubber) but my question is will this cause KR or is that only caused by metal touching metal? I can live w/ the extra vibration...it's better than hearing/feeling the y rattle against the car.
Thanks

It's vibration conducted up the pipe to the heads that
causes the false-KR grief. I don't think rubber will be
"sharp" enough an impact to "ring your bell" but any
metal-metal buzz/rattle could be.
You might want to try loosening the Y-pipe mount and
clamps, shim all of the tight passes between it and the body
with pieces of 1"x2" or 1"x4" wood, put the floor jack to
the low point until you start to raise the body and then
retighten. This should give you enough clearance not to
bang (lather, rinse, repeat).

I understand all except putting the jack to the "low point"...where do you mean? Are you saying to jack under the y-pipe until the body start to raise and then tighten everything while the wood shims are in place?
