94 civic - rear exhaust joint leak?
 

I am having a problem with the new exhaust on my 94 4door civic LX - it's a
stock replacement walker system.

The rear pivot joint in front of the rear axle leaked a lot, even with a new
donut and spring bolts. We ended up using exhaust goo to seal the joint.
We also had to toss the springs and bolts in favor of threaded rods - no
more exhaust leaks but now we get vibrations since it is a solid connection.

What's the solution? The retailers claims he never had a complaint on that
model before. He offered me a replacement donut gasket, but it was exactly
the same as the other new one, so I didn't take it.
