Seems a bit of a pointless gimmick to me to be honest. (Just an old farts opinion )Tarzan wrote: ↑Wed Jan 15, 2020 9:31 am has anyone installed this accessory?

But then, mine is stuck permanently open anyway and I'm quite happy with that.

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.Zikim wrote: ↑Wed Jan 15, 2020 10:14 am I can't see the point in it.

Ps, we’re at cross purposes here, the 35i/35is models use a different form of exhaust flap control to the 20i rangeSmartbear wrote: ↑Wed Jan 15, 2020 10:55 amI 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.Zikim wrote: ↑Wed Jan 15, 2020 10:14 am I can't see the point in it.

According to my research, only turbo engines have an exhaust valve.
The valve in normal use is not constantly open in fact it depends on the regime.
This gadget allowed to make noise when we want to finally if I understood correctly.
