	Go Fast Bits Basic Dump Valve Evo Basic by name but not by quality. Sporting the same unique internal features and quality found in all GFB valves, tests prove that the Basic can flow up to 40% more than other valves on the market of the same size and shape. This is actually one of the highest flowing valves in the GFB range owing to the large venting area of the 5 hole pattern. This capacity makes the basic a great choice for big horsepower and drag engines and all at an affordable price. Please choose colour requirement below. Price: £105.99

	Go Fast Bits Plumback Dump Valve Evo Designed as a replacement for factory re-circ valves and for those who wish to remain a little more anonymous. The Plumback is capable of holding and flowing more boost than factory valves. This results in better throttle response and boost stability whilst remaining silent. If your factory valve is not up to the task and you dont want any noise, this is the valve for you. Please choose colour requirement below. Price: £142.99

	Go Fast Bits Bovus Maximus Dump Valve Evo Got a larger turbo system and want lots of noise? Twin stage trumpets make this a very responsive valve with a flow capacity comparable to the Basic but with a louder discharge. Please choose colour requirement below. Price: £169.99

	Go Fast Bits Hybrid Dump Valve Evo The Hybrid is the choice if you want a more subdued but audible blow-off noise or, if you suffer from backfiring with an atmospheric valve. Its two seqentially opening outlets recirculate some air back into the inlet and preventing backfiring and idle issues whilst the rest is vented to air. Please choose colour requirement below. Price: £169.99

	Go Fast Bits Stealth FX Dump Valve Evo GFB's Flagship model the unique patented Stealth system allows you to adjust the bias between the trumpet and the plumb back outlet giving you complete control over how loud your shifts are.

	Forge Closed Loop Dump Valve Evo 4/5/6/7/8 Forge Motorsport Closed Loop Dump Valve to suit Evo 4 - 8 Made from billet aluminium, this recirculating diverter valve dumps the charge-air back into the air intake system keeping external noise to a minimum. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably. Price: £146.99


	Forge Piston Ram Dump Valve Evo 4/5/6/7/8 Forge Motorsport Ram Dump Valve to suit Evo 4 - 8 Made from billet aluminium, this atmospheric diverter valve dumps the charge-air to atmosphere creating the "Whoosh" sound most commonly associated with rally cars. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably. Unlike the Diaphragms valves this uses a single piston single spring to prevent the valve from leaking air into the intake system at idle. This prevents the diverter valve from suffering any of the failures associated with single piston and diaphragm type diverter valves. Price: £146.99


	Blitz Super Sound Dump Valve Evo 1 - 8 Blitz dump valves are supplied with a full fitting kit and interchangeable trumpets for different sounds. The main purpose of the dump valves is to improve the response of the turbo by quickly releasing the boost pressure before the turbo stalls. Price: £284.99
