This adapter mounts between the OEM bypass valve/solenoid and the charge pipe, causing the unused charge air to vent to atmosphere (VTA), producing the distinct sound that all turbo owners know and love! The adapter bolts right in with the included longer bolts; no other modifications or tuning are required.

Precision CNC machined from high-quality aircraft-grade billet aluminum, it is available in 4 different colors.

Installation is simple, and all mounting hardware is included.
