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.
