I know the correct fix for Warpspeed Y pipe hitting sway bar causing vibrations at times is to replace the mounts, but I don't want to put any more money into car at this time. Any ghetto suggestions to cushion pipe and muffle noise?

 

pull the mount and fill them with 3m window weld

 

get a strong metal pipe with a wheel attached, mount it to the oil pan. make sure the pipe is a 1/2" or so too tall. that way it will push up on the engine a bit to keep the mounts from sagging. you'll be the first 5 wheel max!!! :

j/k

try and find some used mounts at a wreckers to save money.
