Land Rover Part Number: NTC4426 - Exhaust Downpipe
NTC4426 is an exhaust downpipe that routes exhaust gases from the turbocharger into the vehicle's exhaust system on 2.5 Diesel Turbo (19J) Defender 90 and 110 models up to VIN FA450140. Fitted as the front section of the exhaust, it carries high-temperature gases and must resist heat cycles and vibration; over time corrosion or fatigue can produce cracks or holes that cause exhaust leaks, increased noise and loss of exhaust back-pressure. Replacing a damaged downpipe restores a sealed path for exhaust gases and requires correct alignment at the turbo outlet and adjoining exhaust sections to ensure a proper flange seal.

Frequently Asked Questions
The NTC4426 connects the turbocharger outlet to the rest of the exhaust system on 2.5 Diesel Turbo Defenders, channeling hot exhaust gases away from the turbo while preserving the exhaust flow required for correct turbo operation. Common failure modes are corrosion, cracks at welds or flanges and gasket leaks, which typically present as visible exhaust leaks, louder running or reduced turbo response. Correct flange alignment and a good seal are essential when fitting a replacement to prevent further leaks.
