Just a quick question, I have been told that if you unplug the valve on the drivers side exhaust it can change the 'tone' on the engine, does anybody have any experience doing this? Is it worth while? does it cause any problems? And does any body have any pictures/instructions on how to do it?

I assume you mean the exhaust valve on the S2 111S? You can either unplug the red vacuum pipe at the right tail pipe and block the pipe or do this at the inlet end. Can't say I noticed to much difference but have gone aftermarket now.
