So, searching for an aftermarket bypass valve for the 2015 Barina/Sonic RS that didn't cost a fortune, and I found that the Ford Focus RS mark 3 matches the OEM bypass valve.. So, bought this https://gfb.com.au/products/blow-of.../dv-plus/dv-t9360-suits-ford-focus-rs-detail/
And, yes it fits perfectly. Bit stronger boost, nice pigeon dose sound at low throttle, and it has an adjustment screw to tighten or loosen the amount of bypass-ness.
Much cheaper option than the Forge valve, which I had been looking at buying.
