The Mk7 Golf R and Audi 8V S3 use a bigger turbo than the GTI and A3, which is great for performance, but bad for fitting diverter valves!
GFB has the largest and smartest range of diverter and blow-off pressure relief/reducing valves on the market, from the silent Plumb Back type to ear shattering dump valves, the TMS Turbo Management Solution range has a product to suit your needs.
