Part Number: 36A253181AA

Restore the signature deep, resonant growl of your Bentley Bentayga V8 with this Genuine OEM Rear Exhaust Section. This assembly is precision-engineered to balance high-performance exhaust flow with the refined acoustic “purity” that defines the Bentley driving experience.

Technical Specifications

• Compatibility: Specifically tuned for the Bentley Bentayga 4.0L V8 Twin-Turbo (Gasoline/Petrol models).

• Section: Rear Silencer / Muffler Assembly.

• Material: High-grade, heat-resistant T304 Stainless Steel for maximum corrosion resistance.

• Configuration: Dual-inlet/Dual-outlet design, optimized for back-pressure management.

Performance & Engineering Features

• Acoustic Tuning: Unlike the W12 variant, the V8 exhaust is designed with specific internal baffles to highlight the rhythmic “pulse” of the V8 firing order while eliminating cabin drone at highway speeds.

• Thermal Efficiency: Features integrated heat shielding mounts to protect the surrounding air suspension and fuel system components from extreme exhaust temperatures.

• Valved Technology: Designed to work seamlessly with the vehicle’s Drive Dynamics Mode, opening internal flaps in “Sport” mode for a more aggressive soundtrack and closing them in “Comfort” for near-silent operation.

When to Replace Your Exhaust

While stainless steel is durable, high-performance systems can require replacement due to:

• Internal Baffle Failure: A “metallic rattling” sound from inside the muffler usually indicates that an internal weld or baffle has vibrated loose.

• Valve Actuator Seizure: If the exhaust tone no longer changes when switching drive modes, the electronic actuators on the 36A253181AA unit may be faulty.

• Impact Damage: Being the lowest point of the rear chassis, the mufflers are susceptible to damage from road debris or steep inclines.

Fitment & Installation Note

Exhaust Tips: Please note that this part number typically refers to the muffler assembly itself. The chrome or black exhaust finishers (tips) are often separate trim pieces that bolt onto the bumper or the end of this pipe.

Verification Required: The suffix “AA” is specific to certain model years and emissions standards (e.g., GPF vs. non-GPF equipped vehicles). To ensure this unit matches your vehicle’s factory tune and mounting points, please provide your VIN at checkout.
