Milltek Exhaust New Defender L663 90/110 Diesel Model Rear Silencer Bypass

Upgrade your Land Rover Defender L663 D200, D250, D300 or D350 with the Milltek Rear Silencer Bypass. Designed specifically for diesel-powered Defender 90 and 110 models, this high-quality exhaust upgrade delivers a deeper, more purposeful exhaust note while improving exhaust gas flow.

Replacing the restrictive rear silencer with a free-flowing bypass section helps reduce backpressure and gives your Defender a more pronounced, aggressive character without compromising its everyday usability. The lightweight construction and precision-engineered design provide a direct-fit solution, making it an ideal upgrade for both road and off-road vehicles.

Premium T304L Stainless Steel Construction

Manufactured in the UK by Milltek Sport, this rear silencer bypass is produced from high-quality T304L aircraft-grade stainless steel, selected for its excellent strength, corrosion resistance and long-term durability.

Milltek's mandrel-bent tubing maintains a consistent internal diameter through every bend, promoting smooth and efficient exhaust gas flow. The system is also designed with increased bore sizes to maximise flow while retaining strong mid-range performance.

From the pipework through to the exhaust components, Milltek maintains a high standard of construction throughout. Each system is designed, developed and manufactured in-house in the UK, ensuring exceptional quality and precision.
