Suprisingly not. The only real difference (other than the far better sound) is if you give the car full throttle from relatively low rpm you get a resonance noise from the system which resembles an M3 CSL under the same condition.

There is no droning whatsoever and the common droning noise associated with the stock system at motorway cruising speeds is eliminated completely.

Anyone who wants to hear the system on my car or look at one in the flesh (we stock them at all times) is more than welcome to call in to see me?
