Mid-to-Rear Exhaust | Dual-Valve Sound Control | 89mm Mid-Pipe Upgrade | Premium 304 Stainless Steel & Lightweight Titanium Alloy

Upgrade Your 2021 Mercedes-Benz CLS 450 C257 3.0T M256 with GFC Mid-to-Rear Exhaust System, Featuring Dual Mufflers, Dual Electronic Valves, Dual Outlets, and an Upgraded 89mm Mid-Section.

Engineered specifically for the Mercedes-Benz CLS 450 C257 powered by the sophisticated 3.0L turbocharged M256 inline-six engine, this high-performance GFC exhaust system optimizes gas evacuation to unleash the deep, refined acoustic character of Mercedes’ straight-six powerplant. Designed with a custom dual-muffler architecture, integrated dual electronic valves, and an enlarged 89mm mid-section piping, it allows you to switch effortlessly between a civilized, drone-free daily cruise and a roaring, athletic sport exhaust note at the push of a button.

Crafted for Four-Door Coupe Performance Formed to match the sleek, elegant rear styling of the CLS class, this system reduces backpressure to improve turbo spool and throttle response. Built in your choice of premium 304 stainless steel for rugged durability or lightweight titanium alloy for maximum weight savings and an enhanced metallic resonance.

🔥 Key Feature

  • Dual Mufflers with Dual Electronic Valves Features a balanced dual-muffler layout paired with dual electronic valves to provide precise, on-demand control over exhaust flow, volume, and tone.

  • Dual-Mode Acoustic Versatility Keeps the exhaust quiet and serene during daily executive commuting when the valves are closed, while opening up wide to unleash an athletic, deep straight-six exhaust growl and crisp gear-change notes under acceleration.

  • Upgraded 89mm Mid-Section Piping Incorporates high-flow 89mm diameter mid-pipes to maximize exhaust scavenging and support high-output performance tuning for the M256 engine.

  • Clean Dual-Outlet Design Engineered to integrate seamlessly with the factory rear bumper cutouts and trim bezels for a pristine, factory-finished aesthetic.

  • Dual Material Choices (Stainless Steel & Titanium) Offered in high-grade 304 stainless steel for robust longevity or optional lightweight titanium alloy to significantly drop vehicle weight and enhance exhaust resonance.

  • Precision TIG-Welded Finish Expertly hand-welded using TIG techniques to guarantee smooth internal transitions, structural strength, and a reliable, leak-free seal.

  • Direct Bolt-On Factory Fitment Engineered to match factory catalytic converter connection points and OEM mounting hanger locations tailored specifically to the Mercedes-Benz C257 platform.
