The Weistec M276 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 M276 engine comes equipped with electronically actuated bypass valved in the turbo compressor coverd that recirculate back into the compressor inlet for near silent operation. With the M276 VTA Adapter, there will be no check engine light as the factory valves are still used, and no tuning or ECU calibration is required.
