ASR Exhaust Flap Control Module. Exhaust Sound with Flaps fully open.

You just need to spend a couple of quid on a Golf R blanking connectors and hey presto, valves permanently open. Did it to mine. Love it

I bought those first off. The sound when the car used Cylinder deactivation was a droning horrible noise. As I wanted to continue using cylinder deactivation these connectors which keep the exhaust valves permanently open were taken straight off. With the ASR flap controller I have the flexibility to open and close the flaps when I want to.
