Why enthusiasts choose this system

• Auto mode lets you set a specific RPM for the valves to open for the ideal balance of volume and comfort
• One piece layout promotes smooth gas flow and hassle free alignment on the hangers
• 3D scanned and reverse engineered for true OE-like fit on the Tiguan R platform
• In-house dyno development delivers genuine performance gains and crisp response

Sound on demand

Valves open gives an authentic motorsport note and maximum presence. Valves closed keeps things refined for early starts and long journeys. Use AUTO to let the system open at your chosen RPM for a clever, set-and-forget driving experience. The remote connects through the OBDII port for an easy, plug in setup.

OPF and GPF ready

Supplied with an OPF solution where required so cars equipped with a particulate filter can run this catback without warning lights. No ECU coding is needed.

Engineered the right way

The OEM exhaust is 3D scanned to capture routing, diameters and bend geometry. Simulation work refines gas flow, temperatures and back pressure to deliver performance and tone. 7-axis CNC bending preserves cross-section roundness to minimise turbulence, while crisscross and overlapping weld techniques and direct spot welding increase strength at high temperature joints for long term reliability.

Vehicle compatibility

• Volkswagen Tiguan R - EA888 MK2
• Volkswagen Tiguan 2.0 TSI 320 4Motion - 2020 onwards
