Not sure they have.

However I have Eisenmann mid pipes with Eisenmann Sport mufflers which is a proxy since the Eisenmann Sport uses OEM valve control to reduce low rpm noise (just like the OEM exhaust) but the mid pipes have no resonator and result in more throatiness.

The initial throttle response is more real whereas without the mid pipe it just sounds muted on initial response. On the whole it is a much more comprehensive sound than just adding the axleback. Makes the car sound racy but without drone.

It also seems you hear more of the turbo noise with the resonator deleted.
Any links to sound or video clips?
