S4 B8 V6 3.0 2008 on

The Powervalve rear silencer set developed for the S4 V6 3.0 TFSi (B8) provides a spectacular uplift to the pre-existing dynamic V6 sound on the OEM exhaust, and due to the unique way in which we have designed the silencers combined with the variable sound provided by our own unique equalizer technology the experience is totally drone free.

With this setup running on cars just under 500bhp a full system is precluded.
