Exhaust system Capristo Mercedes-AMG CLA45 C117

02MB08403016

Exhaust system for the Mercedes-AMG CLA45 C117 and the Shooting Brake X117. The M133 is the four-cylinder that started the 2.0 turbo AMG line, and the factory system keeps most of its crackle behind a particulate-era silencer.

How it works

The valves stay closed at light load, so cruising noise is close to standard. Opened, the gas path shortens and bypasses the damping chambers, which is where the volume and the sharper response come from. Capristo valves are made in house and the design is patented to keep resonance out of the cabin.

Material and build

T309 (1.4828) stainless steel, rated for continuous temperatures above 600 C, hand TIG welded and polished to a mirror finish in Sundern, Germany, developed on 3D laser scans of the original pipework.

Before you order

• One part covers the CLA45 Coupe and the Shooting Brake;
• Downpipes and sport cats are ordered separately;
• The system is lighter than the standard parts it replaces;
• Installation uses the original mounting points and is reversible.

Capristo Automotive GmbH has built valved exhaust systems since 1990 and holds several patents on its valve technology.
