I've read on a few other forums about the exhaust flaps - or at least the opening of the exhaust flaps, which gives the car a deeper droning sound when under 2000rpm... suppose to be a great mod.
I'm not sure if this is for the R series only... or this can be done on a GTI (which I have, and maybe other models which have dual and single exhaust pipes instead of quad).
If so does anyone know the coding for it, and whether it's decent to do so?
if you could post the coding for turning it on & off that would be great.
If you have any videos of before and after the sound change that would be great too.
thanks again.

I found this from another forum - no idea if this process or coding works
Exhaust Flaps
To keep the exhaust flaps permanently open (Golf R hatch only) and have all four working regardless of mode (or engine restart) you must disable the functionality. To do this there is an important start up procedure - otherwise you will code them permanently closed. To prepare I...
1) started the engine and selected race mode (if gearbox is DSG - select 'sport')
2) turned off the engine
3) turned the ignition back on (didn't start the engine)
4) performed the mod below.
After pressing the coding button (bottom right of the scan button in the image above) you need to select:
Engine Control Module > Coding > (make sure the 'long coding' toggle-switch top right is switched on) then select: Byte 9 (from the options at the top where you can type in byte numbers) > Untick bit 2.
Then click the tick to save changes.
Test this by starting the engine and putting your hands over the outer two exhausts. If there is an obvious stream of air pushing against your hands then you have been successful. To be doubly sure you could switch engine modes and re-check but the Golf always starts up with two exhausts closed regardless of the last mode it was left in.
