^ that's only good advice if you've got a loud exhaust, loud fuel pumps, horny turbo noise, air intake noise etc...on more conservative cars the CAT600 bushes are loud.

The cat bushes transfer a lot  of bearing and diff noise.  Dan is correct.  I have heard them first hand.  My full nolathane in BA and BF are half as noisy . The new round nolathane rear bush with voided sides in the territory are quite as. 

nolathane diff bushs just clocked over 1 year old the other day. done by XFT actually. they charged the guy $995. most of that time has been with me hahahaha!

You also have exhaust, fuel pumps etc though.

 

But even the Super Pro solid bushes I had in my XR6T were considerably quieter than the CAT600 bushes were in my GT.

I love nvh. 

Nothing more sterile than driving a fast car that makes no noise. 

The noise Dan is describing sounds like the diff is about to fall out.  And his was a new car 

^This. Engine and exhaust noise = 

Diff sounding like it's trying to punch through the floorpan and take the rear end of the car with it =

well im not really any closer to figuring out whether I should go stock or superpro haha. I guess ill go with the superpro since IMS recommend buying them along with their diff kit anyway.
