Description

Product Information

Unleash the full potential of your 2021+ Land Rover Defender P525 90, 110, and 130 (L663) 508PS 5.0L Supercharged V8 with the BlackBoost Catless Downpipes. Precision-engineered using advanced CAD technology, these high-flow downpipes deliver an OEM-style fit while significantly improving exhaust flow, reducing back pressure, and producing a deeper, more aggressive exhaust note.

Constructed from premium T304 stainless steel with mandrel-bent tubing, laser-cut brackets, and hand TIG-welded construction, they offer exceptional durability and long-lasting performance. By replacing the factory catalytic converters, the system enhances throttle response, increases horsepower and torque, and provides the ideal foundation for additional performance upgrades, including ECU tuning, intake systems, and performance exhausts.

Designed as a direct bolt-on replacement using factory mounting points, the BlackBoost Catless Downpipes are compatible with BlackBoost and other aftermarket performance upgrades, supporting high-horsepower builds while maintaining precise fitment and reliability.

Note: This product is intended for off-road and racing use only and is not street legal. ECU tuning is required to remove the Check Engine Light (CEL) after installation.
