Unleash Maximum Flow & V6 BiTurbo Acoustic Power — CEES Mercedes-Benz CLS320 / CLS400 (C218) 3.0T Valved Sport Catback Exhaust System
Transform the acoustic personality and exhaust gas velocity of your four-door coupe or shooting brake with the CEES Valved Sport Catback Exhaust System, engineered exclusively for the Mercedes-Benz CLS320 & CLS400 C218 / X218 3.0T V6 BiTurbo (2015–2018). Precision-crafted for the M276 3.0L twin-turbo platform, this system combines oversized mandrel-bent tubing with high-response electronic valves operated directly via wireless remote key fobs. Effortlessly toggle between quiet, drone-free executive cruising and an aggressive, unrestricted V6 BiTurbo sport growl at the push of a button.
🚀 Engineering Highlights
- Dual Electronic Valve System: High-temperature electronic actuator valves operated directly via included wireless remote key fobs. Open valves for maximum flow velocity and an aggressive AMG-inspired sports growl, or close them for quiet, refined cruising with zero cabin drone. The 12V plug-and-play actuators eliminate complex vacuum lines.
- Optimized BiTurbo Exhaust Scavenging: Smooth mandrel-bent stainless steel piping drastically minimizes backpressure, accelerating twin-turbo spool and sharpening throttle response across the entire RPM range.
- Aerospace-Grade T304 Stainless Steel: Handcrafted from premium heat-resistant T304 stainless steel with precision TIG welds for lifetime structural durability and corrosion resistance under extreme load.
- Acoustic Drone-Free Chamber Design: Advanced internal muffler packing tuned to eliminate highway low-frequency cabin resonance while amplifying an aggressive mechanical exhaust note on acceleration.
- 3D Laser-Scanned OEM Fitment: 100% bolt-on replacement utilizing factory mounting points and exhaust hangers without cutting, welding, or rear-bumper modification.

FAQ
1. How do the electronic valves operate on the Mercedes CLS320 / CLS400?
The system features dual high-precision electronic valves. Using the included wireless remote key fobs, you can open the valves for aggressive sports sound and maximum exhaust gas velocity, or close them for refined executive cruising comfort. The actuators plug directly into vehicle 12V power without requiring vacuum lines.
