All newer cars have that isolator joint on them and they still hang/dampen the rest of the exhaust.
I'd think you'd hear the exhaust vibrations resonating in the pipes and through the frame. Dunno.

If the only flex point is at that front section and everything else is rigid mounted to the frame I think its still going to break/shear one of the mounts off near the tailpipe. These are long cars and since he's running the pipes all the way out the back, you'd want to dampen the pipes along the way with rubber or even better, urethane. Will create less vibration throughout the cabin as well as allow the tail sections the ability to move around a little as the car is running. Just my 2 cents ...

The rest of the mounts have urethane mounts at each point.

How do you like trans mount? Great for isolating vibrations!

I'll add that I worked enough with vehicle NVH issues that I am sensitive to noise transmission paths. Putting rubber dampeners in the joints (sandwich style) so it's not steel-on-steel would help.

Man, that thing is just too cool. And generally I'm not a huge Halibrand guy, but those wheels just fit that car. Awesome job.
