Mercedes-Benz Mercedes GLS 2016-2019 Exhaust Specifications

The exhaust system is designed to be compatible with all 2016-2019 Mercedes GLS models, including the GLS 450, GLS 550, and AMG GLS 63 variants. It adheres to OEM specifications, ensuring proper fitment and performance. However, slight modifications may be required for AMG models due to their enhanced performance features. Always verify compatibility with your specific trim and engine configuration before purchase.

Regular maintenance for the exhaust system includes inspecting for rust, cracks, or leaks every 12 months or 12,000 miles. Ensure all connections and hangers are secure. Cleaning the exterior with a mild detergent can prevent corrosion. For optimal performance, replace gaskets and seals every 50,000 miles. Adhering to these guidelines ensures longevity and maintains exhaust efficiency.

To install or replace the exhaust system, first, lift the vehicle securely using a jack stand. Remove the old exhaust by detaching clamps, hangers, and bolts. Align the new exhaust system, ensuring proper fitment with the catalytic converter and muffler. Secure all connections with new gaskets and bolts. Tighten clamps and hangers, then lower the vehicle. Test for leaks and ensure proper alignment.

Unusual noises from the exhaust system, such as rattling or hissing, often indicate loose components, leaks, or damaged parts. Inspect the system for loose clamps, hangers, or cracks. Tighten or replace damaged parts as needed. If the issue persists, check the catalytic converter and muffler for internal damage. Professional diagnostics may be required for complex issues.

To optimize performance, consider upgrading to a high-flow catalytic converter or performance muffler. Ensure the exhaust system is free of leaks and properly aligned. Regularly clean the exterior to prevent corrosion. For enhanced sound and efficiency, pair the exhaust with a tuned ECU. Always follow manufacturer guidelines to avoid voiding warranties or causing engine damage.
