Well today I finally got round to bypassing the Rear BCS with some new silicone vacuum hose.
I fitted a Collins DV at but was disappointed that it sounded no louder than the Baileys it replaced. I read that bypassing the rear BCS made a big difference so thought I'd go for it.
I followed the diagram that Wavey created (cheers dude, made it soo simple).
So here are the comparison videos...
I did a before video but tbh you cannot even hear the dump valve, just engine noise. So here is the before video...
Rubbish isn't it!!
So here is the video with BCS setup bypassed, we did two lol
Its sooo much louder its unreal! And on the road it seems to dump much more frequently.
So all in all it was a big Win for today
I also sorted out a coolant leak and oil leak which was handy.
