Unleash the Turbocharged Inline-6 AMG Roar — CEES Mercedes-Benz CLS53 AMG 3.0T Valved Sport Exhaust System
Engineered specifically for the Mercedes-AMG CLS 53 4MATIC+ (C257 / 2019–2023), this premium Valved Sport Exhaust System unlocks the exhilarating acoustic potential and performance of the 3.0L Turbocharged Inline-6 engine with EQ Boost. Designed to integrate directly with your factory OEM exhaust valve actuators, this system provides seamless dynamic sound control—refined, drone-free touring in Comfort mode, and an aggressive, crackling AMG sport growl in Sport and Sport+ modes.
🚀 Engineering Highlights

Switch seamlessly between quiet cruising and wide-open AMG sport sound directly via your steering wheel controls and AMG Dynamic Select modes—no aftermarket wiring or remotes needed.
- High-Flow Performance Architecture: Mandrel-bent piping geometry eliminates exhaust flow restrictions and reduces backpressure, sharpening throttle response and optimizing turbo spool across the entire rev range.
- Master-Tier Craftsmanship: Precision hand-TIG welded from premium corrosion-resistant T304 Stainless Steel for maximum thermal durability and structural integrity under high exhaust temperatures.
- 3D Scan Precision Fitment: Developed utilizing high-definition 3D laser scanning of the CLS53 AMG chassis for a 100% direct bolt-on installation utilizing factory mounting points and original AMG quad exhaust tip outlets.

FAQ
1. How does the OEM valve system work on this exhaust?
This system is custom-engineered with precision mounting brackets designed to accept your factory Mercedes-AMG electronic valve actuators. You retain 100% original vehicle integration—changing drive modes (Comfort, Sport, Sport+) or pressing the factory exhaust console button continues to operate the exhaust valves exactly like OEM.
2. What is the difference between Catback and Full Exhaust?
The Catback Exhaust includes the midpipe and valved rear mufflers, connecting directly to your factory downpipes. The Full Exhaust includes both the high-flow turbo downpipe (available in Catless or 100/200/300-cell high-flow catalytic options) and the valved catback system for maximum exhaust flow, turbo spool, and sound output.
3. Will this exhaust fit my CLS53 AMG without modification?
Yes. The system is 3D-scanned to the factory C257 chassis for a 100% direct bolt-on fit, utilizing OEM mounting brackets and reusing the factory rear bumper exhaust outlets, with no cutting or welding required.
4. Will this exhaust system trigger a Check Engine Light (CEL)?
• Catback Exhaust: No. Installed downstream of factory catalytic converters and sensors, it does not alter emissions equipment and will not trigger a CEL.
• Full Exhaust: To ensure trouble-free operation, all Full Exhaust orders include a complimentary O2 sensor CEL fix spacer designed to isolate secondary oxygen sensor readings and prevent catalytic efficiency fault codes.
5. Are you a direct manufacturer?
Yes — CEES Exhaust is a direct manufacturer based in Guangdong, China. We build our exhaust systems in-house with strict quality control, providing enthusiasts with race-proven engineering at factory-direct pricing.
