Switchable Valved Sports Exhaust for VW Tiguan Mk2 2.0 TSI EA888 2017 onwards – Quad Outlet – GP508S

Give your second generation Tiguan a serious soundtrack and sharper response with Stone’s valve controlled system from the catalytic converter back. Purpose designed for the VW EA888 powered 2.0 petrol range including 330 FSI and 380 FSI, this upgrade brings a deeper tone, noticeably freer flow and OEM style fitment. We run this setup on our own cars and our customers consistently praise the sound quality, the finish and the slick valve control.

  • Switchable valves with handheld remote for quiet, loud or automatic operation
  • Plug in OBD2 controller for fast installation and simple control
  • Two electronically actuated flaps for refined cruising and aggressive note on demand
  • Quad tailpipe layout for a purposeful look at the rear
  • Developed using full system 3D scanning for factory level alignment
  • Dyno developed and tuned for a clean, sporty tone with no motorway resonance
  • One piece precision bent pipework for smooth gas flow and reliability

Valve control made easy

Choose when you want stealth or full character. The supplied remote offers three modes: valves closed for early starts and daily use, valves open for full volume, or AUTO to switch at a set RPM.
