Forge Motorsport Alloy Atmospheric Dump Valve for Subaru Impreza
The Forge Motorsport Alloy Atmospheric Dump Valve is designed to fit Subaru Impreza models from 2001 onwards, including the 2009 GR STi. This high-quality valve is made from billet aluminium and hand polished in the UK, ensuring durability and a sleek appearance.
When the throttle is lifted, this atmospheric diverter valve releases the charge-air to the atmosphere, creating the iconic “Whoosh” sound commonly associated with rally cars. Not only does this valve enhance the auditory experience, but it also improves throttle response and provides a higher clamping load to maintain boost pressure more reliably.
The Forge Motorsport Alloy Atmospheric Dump Valve comes with everything you need for installation, including the valve itself, a 34mm Blanking Plug, and a Forge Sticker. If you want to customize the valve to suit your engine’s specific needs, a spring tuning kit is available separately.
At Progressive Parts, we offer fitting services for this product at our performance workshop. Our experienced technicians can ensure proper installation and optimal performance. If you have any questions about compatibility or need assistance, our knowledgeable team is here to help.
Upgrade your Subaru Impreza with the Forge Motorsport Alloy Atmospheric Dump Valve and enjoy the benefits of improved throttle response and the exhilarating “Whoosh” sound. Order yours today!

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
