Mercedes-Benz C218/X218 CLS550 Primary Pipes

Improve exhaust flow and engine response on your 2011–2018 Mercedes-Benz C218/X218 CLS550 with Primary Pipes engineered to reduce restriction while retaining the factory exhaust manifolds for a seamless integration with your stock exhaust system.

These Primary Pipes function as the downpipe section, replacing the restrictive factory primary components to increase exhaust flow and deliver a more aggressive exhaust character without modifying the stock manifolds.

Available in two configurations:

Race Pipes – Decat / Cat Delete – Maximum exhaust flow with no catalytic restriction, delivering a louder, more aggressive tone and improved throttle response.

Street Pipes – High Flow Catalytic – Equipped with performance High Flow catalytic cores to improve exhaust flow while maintaining a more street-oriented balance. Street Pipes are available in 100 cell, 200 cell, or 300 cell options, allowing you to choose the level of flow, sound, and emissions control that best suits your setup.

Constructed using TIG welded joints and mandrel-bent tubing for smooth exhaust flow, precise fitment, and long-term durability under high heat and load.

Designed as a direct bolt-on upgrade using factory mounting points, this setup installs without cutting or welding and integrates seamlessly with stock or aftermarket exhaust components.
