Decided to give fitting a GFB Diverter Valve a go...Was a lot easier than I thought!
Make sure you do the bolts up tight! Fitted one a few months back. Just checked - one bolt missing completely, the second undone, but not gone and the third up tight..... luckily...
Cheers - will do! Went for a drive after and checked once the engine had cooled, but will check again tomorrow after a longer commute.
Didn't really notice any noise difference though
