Zikim said:I can't see the point in it. The valve's primary function is to make the exhaust quieter on first 30 seconds on start-up when the engine revs faster and fuel is enriched to get the Cats to work efficiently as soon as possible. After this initial period the flap opens, why would you want to make an already quiet exhaust quieter on normal driving?
Owners usually make the Golf Tee mod to increase the noise![]()

I don’t think the flaps opened constantly after warm-up but at higher revs/throttle openings, mines permanently open & produces more sound than it used to. :?
