J M Stott Posted August 25, 2014 Share Posted August 25, 2014 Hi all, 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? Thanks James Link to comment Share on other sites More sharing options...
un1eash Posted August 25, 2014 Share Posted August 25, 2014 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.
