Simply fit these in place of the standard rear boxes to hear more of that V6. I found the noise level when cruising to be as quiet as standard, with a nice level of added sound quality and volume when giving it the beans. Easy to keep clean, and being stainless steel, they should last a while
Powervalve exhaust boxes for B8 S4
Powervalve exhaust boxes for B8 S4
Pair of rear stainless steel silencers bought from BCS Powervalve in Aug '15 and used on my B8 S4. These provide a great change in noise quality, adding a little more throatiness and deep grumble while accelerating - they won't do your head in, and there's no drone from these either when fitted to a standard system.

While both boxes are in fantastic condition, the bits you'll see (the tailpipes) are mint. Looking for £600.
