DESCRIPTION
Isolate Engine Bay Heat. Radically Minimize Backpressure. Unleash the True V8 Biturbo Sound.
The factory downpipe layout on the Mercedes-Benz W218 CLS500 and CLS550 houses restrictive catalytic components that heavily choke the 4.7L M278 engine. This WANMAX RACING Premium Performance Turbo Back Downpipe Set is meticulously engineered to break that bottleneck under all-wheel-drive configurations. By removing the stock catalytic converters in favor of an aggressive straight-through design, it drastically minimizes backpressure, allowing the twin turbochargers to breathe freely and eliminating throttle lag. Armored with an integrated heavy-duty heat shielding wrap, it locks extreme temperatures inside the piping to maximize exhaust scavenging while protecting critical drivetrain seals.
VEHICLE FITMENT
- For Mercedes-Benz CLS500 / CLS550 (4-Door Coupe / Sedan Car) — 2011-2018 (4.7L M278 Twin-Turbo V8 Gas Models, 4MATIC AWD Only)
KEY FEATURES
- Engineered for 4MATIC AWD: Specially designed for the 4MATIC all-wheel-drive chassis, with a precision-routed profile that ensures perfect clearance around the front driveshaft and transfer case for a direct, stress-free bolt-on installation.
- Integrated Heat Shielding: Features a heavy-duty, multi-layer stainless steel mesh wrap over high-heat areas, trapping radiant heat to protect critical surrounding components like AWD seals and wiring harnesses from thermal degradation.
- Optimized V8 Power Gains: The aggressive, straight-through catless piping drastically minimizes exhaust backpressure, letting the 4.7T BiTurbo V8 breathe freely for significant gains in horsepower and zero throttle lag.
- Stage 1/2 Tuning Compatible: Specifically built to handle the increased airflow and extreme thermal demands of tuned M278 engines, maximizing exhaust gas scavenging to deliver smooth, linear power delivery.
- Acoustic Vibration Dampening: The specific wall thickness combined with the outer thermal mesh absorbs harsh metallic rasp and annoying cabin drone, refining the M278 exhaust note into a deep, premium exotic growl.
