The Ultimate BiTurbo V8 Symphony — CEES Mercedes-Benz W218 CLS63 AMG M157 Valved Catback Exhaust System
Transform the driving dynamics and acoustic profile of your Mercedes-Benz W218 CLS63 AMG with the CEES Valved Catback Exhaust System. Specifically engineered for the M157 5.5L V8 BiTurbo engine, this premium exhaust replaces the restrictive factory mufflers to deliver a deep, aggressive AMG growl under hard acceleration, while maintaining a refined, drone-free cabin during daily cruising.
🚀 Engineering Highlights
- Electronic Valve Control: Complete control over your exhaust note. Utilizing high-torque electronic valve actuators and an included wireless remote, switch instantly between a subdued "Comfort" mode and a raw, unrestricted "Sport" mode.
- High-Flow 76mm Architecture: Precision mandrel-bent 76mm (3-inch) piping optimizes exhaust gas velocity, significantly reducing backpressure to sharpen throttle response and unleash hidden horsepower from the BiTurbo V8.
- Master-Tier TIG Craftsmanship: Hand-welded from your choice of premium T304 Stainless Steel or ultra-lightweight Grade 5 Titanium to withstand extreme thermal loads.
- Precision Fitment: Engineered via high-definition 3D chassis scanning for a direct bolt-on installation—integrates perfectly with factory downpipes or CEES upgraded downpipes.

FAQ
1. Will this exhaust cause a check engine light (CEL)?
No. As a catback exhaust system, it installs after the factory catalytic converters. It will not alter emissions parameters or trigger a check engine light.
2. What is the difference between SS304 and Titanium?
The T304 Stainless Steel version offers excellent durability and a deep, traditional V8 rumble. The Grade 5 Titanium version provides massive weight savings and produces a slightly higher-pitched, more exotic exhaust note.
3. Do I need an ECU tune with this catback system?
An ECU tune is not required for a catback exhaust installation. However, pairing this exhaust with CEES high-flow downpipes and a Stage 2 tune will maximize your AMG's performance.
4. Are you a direct manufacturer?
Yes — as a direct manufacturer based in Guangdong, China, we eliminate middlemen to deliver premium, track-tested exhaust systems with strict in-house quality control and competitive pricing.
