Lamborghini Urus – EPA-Compliant 400 Cell High-Flow Downpipes

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

Introducing Our NEW 400 Cell EPA-Compliant Downpipes for the Urus

The Lamborghini Urus delivers supercar-level performance in an SUV platform — but factory catalyst restrictions limit the full potential of its 4.0L twin-turbo V8. Our NEW EPA-compliant 400 cell high-flow downpipes unlock improved exhaust flow, sharper turbo response, and a deeper, more aggressive sound profile — all while maintaining emissions compliance standards.

Engineered specifically for the Urus platform, these downpipes represent the next evolution in compliant high-performance exhaust technology.

Why 400 Cell?

• EPA-Compliant 400 Cell Catalysts: Designed to increase exhaust flow while maintaining compliance standards.
• Improved Turbo Efficiency: Reduced restriction enhances spool characteristics and throttle response.
• Enhanced Exhaust Tone: Deeper low-end presence with sharper turbo acoustics and a more exotic character.
• Balanced Performance: Noticeable gains without sacrificing daily drivability.

Performance & Engineering

• Optimized Flow Path: Reduces backpressure while maintaining catalyst efficiency.
• Mandrel-Bent Tubing: Smooth internal transitions for maximum airflow.
• Precision TIG Welding: Built to withstand extreme heat cycles and boost pressures.
• Direct OEM Fitment: 100% bolt-on design using factory mounting locations.
• Designed to Pair Perfectly with Valvetronic Titanium Exhaust Systems

Sound Profile

• Stock Exhaust + Downpipes: Noticeable increase in volume with enhanced turbo character and deeper tone.
• Valvetronic Exhaust + Downpipes: Maximum transformation — heightened aggression, sharper transitions, and a true Lamborghini-inspired exhaust note.

Construction & Craftsmanship

• Premium high-grade stainless-steel construction
• High-temperature resistant 400 cell catalyst cores
• OEM-style O2 sensor placement
• Engineered for long-term durability under high boost

Important Installation Notes

• Professional installation recommended.
