Bentley Bentayga V8 – EPA-Compliant 400 Cell Catted Downpipes

Precision Engineered for the 4.0L Twin-Turbo V8 • High-Flow Performance •


Introducing Our NEW 400 Cell EPA-Compliant Downpipes for Cayenne

The Bentley Bentayga V8 platform is a masterclass in performance engineering. However, factory catalyst restrictions limit the full efficiency and character of its 4.0L twin-turbo V8. Our NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to reduce exhaust restriction, improve turbo response, and refine the exhaust note — all while maintaining emissions compliance standards.


Why 400 Cell?

  • EPA-Compliant 400 Cell High-Flow Catalysts: Increased exhaust efficiency while maintaining compliance standards.
  • Improved Turbo Response: Reduced backpressure sharpens throttle input and mid-range delivery.
  • Refined Yet Aggressive Sound: Deeper tone with enhanced clarity at higher RPM.
  • Maintained Daily Comfort: Performance gains without sacrificing drivability.

Engineering & Performance

  • Optimized Flow Design: Reduces restriction while preserving catalyst efficiency.
  • Mandrel-Bent Tubing: Smooth internal transitions for consistent exhaust velocity.
  • Precision TIG Welding: Built to endure high temperatures and sustained boost pressure.
  • Direct OEM Bolt-On Installation: Utilizes factory mounting locations.
  • Engineered to Pair with Valvetronic Exhaust Systems

Sound Profile

  • Stock Exhaust + Downpipes: Noticeable increase in depth and presence without overwhelming cabin refinement.
  • Valvetronic Exhaust + Downpipes: Sharper response, increased volume, and a more motorsport-inspired character while retaining Porsche composure.

Construction & Durability

  • Premium high-grade stainless-steel construction
  • High-temperature resistant 400 cell catalyst cores
  • OEM-style sensor placement for proper operation
  • Engineered for long-term reliability under high performance conditions

Elevate the performance and sound of your Porsche Cayenne — engineered with precision, starting at the source.
