re. the exhaust valves as OEM - it is pretty common as it allows manufacturers to get past exhaust noise limits set by regulators and yet make the car fruitier sounding outside of the narrow parameters tested.

866-278-1896 is the number for Eisenhaus. They sell the Kries-Sieg system (I purchased mine through them). Ask for John. He is very savvy with this system. As I noticed you are in the UK, I can call for you if you'd like? I know you'd probably want to hear for yourself but am willing.
Let me know.
