The supplied remote offers ON, OFF and AUTO modes so you can enjoy a quiet start, a refined cruise or a fully open, aggressive tone at the press of a button. AUTO mode lets you set the valves to open at a predefined RPM. Installation is plug and play via the OBDII port and can be completed in minutes.
OPF delete option included
Running an OPF-equipped Tiguan MK2? Stone includes an OPF delete solution free of charge, allowing you to fit the Stone cat-back on OPF cars without triggering error codes. No ECU coding is required to remove OPF faults.
Engineered for flow, fitment and sound
Stone Exhaust engineers 3D-scan the factory system to map pipe routing, diameters and bend angles before optimising for power and tone. The result is a direct-fit cat-back system tailored to the EA888 Tiguan platform with improved exhaust gas flow and that unmistakable Stone sound.
