Forza Exhaust Valve Controller for Aston Martin DBS / DB9 / Vanquish / Virage / Vantage / Rapide / V12 Zagato

Match this Forza kit to the Aston Martin’s original vacuum-solenoid exhaust system before ordering. The listed model families span different generations, so confirm the valve actuation, connector and any required adapter rather than treating the model name as an all-year guarantee.
