Complete exhaust with racing valve CES3 catalytic converter 250 cell Capristo Porsche 987 Boxster Cayman MK2 2009-2012

The CAPRISTO high-performance complete system aims to provide a balanced increase in power, drivability, and sound quality, while also significantly reducing weight. This is achieved while maintaining the CAPRISTO philosophy of "the best of both worlds," which offers the ability to produce an aggressive exhaust note under acceleration and a more subdued sound for city driving. This system has been dyno-tested and has demonstrated an improvement of 25 HP.

This feature is achieved by using vacuum-actuated valve flaps that open and close depending on driving conditions and driver input. At lower engine speeds and during cruising, the valves are closed, producing a deeper exhaust note. With the throttle wide open, the valves open, releasing the full symphony of the engine.

The exhaust valves are controlled by backpressure and via the included Valve Controller Remote, which allows you to permanently control the flaps without the series control being able to intervene. When the exhaust valve system is closed again using the remote control, the series control unit will regain control of the exhaust valves. This allows for precise control of the exhaust based on personal taste and driver tolerance.

CAPRISTO exhaust systems are designed and manufactured using advanced 3D laser scanning, CAD design, digital prototyping, and CNC bending/milling in our factory in Germany. Each system is crafted from high-quality T309 (1.4828) stainless steel and hand-polished to a mirror finish. After extensive research, this specific alloy was chosen for its sonic resonance properties, low weight, and durability that are close to the properties of Inconel (used in F1).

PERFORMANCE HEADLAMPS:

Headlamps utilize a custom design and modified pipe routing compared to stock headers to maximize exhaust flow.

250 CELL SPORT CATALYST:

High-performance sport catalytic converters feature a 250-cell per square inch substrate made from the highest quality materials currently available, designed to improve airflow to your vehicle and increase performance.

The cell count of a catalytic substrate refers to the number of holes per square inch and is a direct indication of the flow capabilities of that substrate. The fewer the holes, the larger the hole needs to be to fill a square inch; a larger hole subsequently allows more exhaust gas to flow.

All that high flow won't help if the substrate is "squeezed" into a small-diameter container or pipe. For this reason, CAPRISTO sport cats come packaged in 5.2-inch packages to maximize exhaust gas flow and valved exhaust system operation.

IMPORTANT

*Exhaust system is designed to install directly into existing OEM mounting points*

*Recommended for off-road and track use only*

Replacing the OEM catalytic converter may activate a CEL (Check Engine Light).

To disable a recurring CEL you will need to tune the ECU or use 02 sensor extensions.
