Unlike single piston or diaphragm diverter valves, this uses counter balanced springs and dual pistons to prevent the valve from leaking air into the intake system at idle. This prevents our diverter valves suffering any of the failures associated with single piston and diaphragm type diverter valves.\u003cbr\u003e\u003cbr\u003eAll Carrot Top Tuning Dual-Piston Atmospheric Valves have been designed and built with the intent of venting 100% of the residual charge air remaining in your forced induction system to the atmosphere at throttle lift. While we have incorporated many elements into the design of the Dual-Piston valves to aid in their compatibility with mass air-flow sensor equipped vehicles, we cannot always guarantee that each individual’s application will be compatible with a valve that vents the charge air into the atmosphere.\u003cbr\u003e\u003cbr\u003eCarrot Top Tuning nor any of it’s Authorised Distributors can assume any responsibility for any adverse effects resulting from the installation of this valve onto a vehicle whose engine-management-system, whether factory or aftermarket, is not capable of compensating for the loss of metered air through a vent-to-atmosphere valve such as this.\u003c\/p\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003e\u003cspan size=\"4\" data-mce-fragment=\"1\"\u003ePackage Includes:\u003c\/span\u003e\u003c\/b\u003e\u003c\/div\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003e2x Blow off Valve\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e2x Plugs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv id=\"disclaimer\"\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff0000;\"\u003e\u003cstrong\u003eProduct Disclaimer:\u003c\/strong\u003e This product is not designed to meet any emissions\/noise standards and is not for street or highway use.

The larger pipes, low-restriction mufflers, and tuned resonators of a well-designed performance exhaust system can make a world of difference on your vehicle. The net result is lower auto exhaust back pressure, more horsepower, more torque, and a much better sound.\u003cbr\u003e\u003cbr\u003eThe most restrictive part of any exhaust system is the catalytic converter. The stock catalytic converter is meant to filter the flow of exhaust gases to reduce the amount of harmful gases into the atmosphere. Because of this, lots of potential performance is restrained. Down Pipes eliminate the stock catalytic converter and reduce exhaust back pressure. By maximizing exhaust flow, this downpipe allows the turbo to spool up and build boost quicker.
