Frequently asked questions

What is the ESR439 Exhaust Box Assembly?
The ESR439 Exhaust Box Assembly is the rear silencer section of the exhaust on the Defender 300Tdi. It attenuates exhaust gas noise as gases pass through the rear of the exhaust line before discharge at the tailpipe. Genuine Land Rover part.
Which vehicles does it fit?
This exhaust box fits the Defender 1987-2006 in 110 and 130 wheelbase with the 2.5L 4-cylinder 300Tdi diesel engine. It's specified for the 110 and 130 wheelbase, so confirm your wheelbase and engine before ordering, as shorter wheelbase or other engines use a different silencer.
What are the signs the exhaust box needs replacing?
A failing exhaust box usually shows up as a louder, blowing exhaust note, a rattle from a broken internal baffle, or visible corrosion and holes in the box body. On the Defender 300Tdi, road salt and age typically rot the rear silencer first, so it's a common replacement.
What's needed to fit it?
Fitting the exhaust box typically needs the clamps and mounting rubbers that support the rear silencer, which may not be included, so check what you're reusing. It's usually a straightforward job on a ramp or axle stands, though corroded clamps often have to be cut off.
