i have an 07 aston martin vantage fuse 22 was out when i bought it sounded amazing one day i revd it hard at a stop light and now its not as loud and no flapping noise coming from exhaust at high revs anyone know why its not as loud any more even with fuse 22 removed please help
I have no idea what fuse 22 is for. The exhaust issue may be due to a valve in the exhaust that no longer opens under full throttle.
