Exhaust Downpipe for the 2.4L Puma diesel engine, forming the front section of the exhaust system between the turbocharger outlet and the intermediate pipe.

This is the non-catalyst (decat) version: it routes exhaust gas from the turbocharger downpipe flange into the exhaust system without an integral catalytic converter, reducing backpressure ahead of the mid and rear silencer sections.

Intended for off-road and competition use. Check local emissions regulations before fitting to a road-registered vehicle.

Frequently asked questions

What is the DA4359 exhaust downpipe used for?
The DA4359 downpipe is the front section of the Land Rover Defender exhaust, connecting the turbocharger outlet to the intermediate pipe. It carries exhaust gas away from the turbo into the mid and rear silencer sections. Land Rover part number GA4359.
Is the DA4359 a decat (non-catalyst) downpipe?
Yes, the DA4359 is the non-catalyst decat version, routing exhaust gas without an integral catalytic converter and reducing backpressure ahead of the silencers. It's intended for off-road and competition use, so check local emissions rules before fitting to a road-registered vehicle.
Which Land Rover does the DA4359 downpipe fit?
The DA4359 downpipe fits the Land Rover Defender up to 2016 and is designed for the 2.4L Puma diesel exhaust system. Downpipe fitment is engine-specific, so confirm your engine variant before ordering.
Why would an exhaust downpipe need replacing on a Defender?
Exhaust downpipes typically fail from corrosion, cracked flanges, or a blown gasket at the turbo joint, which cause exhaust leaks, extra noise and lost boost. A ticking or roaring noise under load is usually the first sign. Replacing it restores a sealed exhaust path.
