The Weistec M177 VTA (Vent to Atmosphere) Adapter is 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. ?The M177 engine comes equipped with electronically actuated bypass valves in the Intercoolers that recirculate back into the compressor inlet for near silent operation. ?With the M177 VTA Adapters, there will be no check engine light as the factory valves are still used, and no tuning or ECU calibration is required.
