ypipe vibrations.
got the headers and ypipe installed over the weekend, lots of ypipe vibrations.
how do i make this go away driving me crazy.

 

Poly motor mounts, bumpstop hanger, header wrap, old valve spring between y-pipe and floor. I've seen them all work. Take your pick. I used a valve spring because I already had one. Most people will say the motor mounts are the best.
