I bought the Superpro polyelast bushes for the diff. 

I know there will be a decent NVH increase but I'll be fitting a 4" exhaust (would prefer to keep the stock catback but the tuner strongly recommended 4") at the same time so that will probably mask it a bit I'm guessing.

I have those bushes and they are fairly quiet until you get on it. I think they are less likely to break compared to most other offerings as they are more or less solid.

 

I have a venom 4 inch dump into their cat section and twin 2.5 "Y" pipe then a stock system after that. It is nice and quiet but will pull 3rd gear skids when it comes on boost at freeway speeds.

 

The bigger exhaust will help make power but in my case there is ample power for the street when turned up. 

 

That is neither here nor there really as we have different model cars and different setups but it's something to compare to I spose.

I have 4" dump, no cat, and then stock catback at the moment and love how quiet it is, but still makes noise at full throttle.

The car makes 500rwhp (370rwkw?) but tuner says a 4" is a good idea.

Also going to be tuning for E85 after the exhaust is on.
