Exhaust system rattles

[Gadzby at aol.com (Gadzby@aol.com)]

Wow, you guys are awesome!  New hangers sounds easy.

I think you're both right.  In addition to the hard metallic sounds coming 
from the muffler area (likely axle beam), muted thumping from the handbrake area 
is intermittantly audible.  When I looked under the car, I noticed the 
resonator is leaving a mark in the soft aluminum heat shield in that area.  Hard to 
say if it's new or not.

The new downpipe has a mostly rigid joint at the manifold.  If the primary 
motion is up as the engine rotates forward, would putting the OEM flex joint 
back in help solve this problem?

actually, it sounds like his exhaust is sitting too high back there, hitting 
the fuel tank heat shield. the reason i say this is that its hitting while 
coasting, where the engine torques forward, which causes the exhaust to 
pivot upward. also, if his hangers arent vertical, there is less vertical 
space per given hanger, which would also make the exhaust sit high.
