Exhaust system with valves and sports catalysts 250 cells capristo mclaren 720s from 2017 02ML11003020

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

The exhaust valves are backpressure-controlled and user-programmable via the included CES-3 control module. The programmable control unit provides 3 modes operated via a remote key fob:

Cruise exhaust valves open at higher RPMs

Sport exhaust valves open at low RPMs and under hard acceleration

Open exhaust valves stay open

Both Cruise and Sport modes can be individually programmed for specific backpressure tolerances to determine when the exhaust valves open. This allows for precise exhaust control 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 at our facility in Germany. Each system is crafted from high-quality T309 (1.4828) stainless steel and hand-polished to a mirror-like finish. After extensive research, this specific alloy was chosen for its sound resonance properties, low weight, and durability, which are close to the properties of Inconel (used in F1).

These high-performance sports catalytic converters feature a 250-cell-per-square-inch substrate, made from the highest-quality materials currently available, designed to improve vehicle airflow 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 that substrate's flow capabilities. The lower the hole count, the larger the hole must 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 can or pipe that's too small in diameter. For this reason, CAPRISTO Sports Cats are packaged in 5.2-inch packages to maximize exhaust gas flow and valved exhaust system operation.

IMPORTANT

Recommended for off-road and track use only

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

To disable a recurring CEL, you will need to tune your ECU or use the Capristo OBD Wizard to digitally clear the CEL in your ECU.

The exhaust system is designed to install directly into existing OEM mounting points
