The Weistec M178 VTA (Vent to Atmosphere) Adapters are designed and manufactured as a complete and simple bolt on solution for attaining the "blow-off" sound that many people are fond of on turbocharged vehicles with out being excessively loud or high pitched. ?The M178 engine in the AMG GT / GT S vehicles comes equipped with twin electronically actuated bypass valves that recirculate back into the airboxes for near silent operation. ?With the M178 VTA Adapters, there will be no check engine light as the factory valves are still used, and no tuning or ECU calibration is required.
