I just spent $171.20 on my E63...
I absolutely love it! It's makes the car so addictive to drive. Someone mentioned earlier in this thread its minimally different at idle and regular driving when driving at low RPM's.
When you get on it has a VERY satisfying sounds that weren't there before. It's more of what you currently have plus some. On full throttle I would say anywhere from 20% to 30% louder and more aggressive. But the louder part is the sound we all love and crave. The mechanical put-puting and rabid barks after gear changes. People around will make no mistake in knowing they have an unholy beast of machine next to them.
I personally think it's an amazing mod and I paid $180 for it. I took it to a regular muffler shop.
The guy told me he put 2 3/4" straight pipes in. I know some people were doing 3", and he said it wouldn't make any difference.
Anyway, great mod for anyone who wants a little more sound.
The OEM resonator is welded onto the rear section of the exhaust, so you have to cut it off. So it will be a bit larger job to re-install it for service visits.
For those that have removed the resonators, any increase in cabin drone at low rpm?
Had this same mod done on another vehicle and although the sound was fantastic the loud drone wore me out over time.

What is that circular metal disk right in the middle of the resonator? It's not easy trying to make out the structure. I wonder how it works.

May pop by my exhaust guy tomorrow.
Just debating if I should take the easy route and get him to put in straight pipes in place of the resonator or have him fabricate an X-pipe.
Also had the option of going with a MagnaFlow pre fab x pipe as below but the guys in the shop thought it would not make too much of a difference so went with the straight pipes first and if need be can have them stick in the x pretty easily.
