TD5 Exhaust Upgrades
TD5 exhaust upgrades for Defender and Discovery 2, including de-cat downpipes, EU2 downpipes, centre straight pipes, fitting kits and selected manifold-related parts for replacing tired exhaust sections and improving exhaust flow.
Start with the vehicle, wheelbase and exhaust section being replaced, then check the product title and fitment notes before ordering. Defender 90, Defender 110 and Discovery 2 centre pipes are different parts, while TD5 downpipes split by front-pipe type and catalyst setup.

Find the right TD5 exhaust parts
TD5 exhaust parts are normally bought by section: downpipe, centre pipe, silencer replacement, fitting kit or manifold-related hardware. Match the pipe to the vehicle and the section being replaced rather than treating every TD5 exhaust part as interchangeable.
| Job | Best place to start | Check before ordering |
|---|---|---|
| Replacing a catalyst front pipe | TD5 de-cat downpipe | Check the existing front pipe and catalyst setup |
| Replacing a standard EU2 front pipe | EU2 TD5 exhaust downpipe | Check that the vehicle uses the non-cat EU2 front downpipe |
| Removing the centre silencer | Vehicle-specific centre straight pipe | Check Defender 90, Defender 110 or Discovery 2 fitment before ordering |
| Fitting or refreshing exhaust hardware | TD5 exhaust fitting kit, clamps, gaskets and mounting parts | Check which joints, hangers and gaskets are being disturbed during the job |
| Manifold repair or repeated manifold movement | TD5 exhaust manifold parts | Use the manifold section where the fault is broken studs, warped manifold faces or repeat manifold loosening |
Check TD5 exhaust fitment before ordering
TD5 exhaust parts are not all split the same way. Some parts are shared between Defender and Discovery 2, while centre pipes are vehicle and wheelbase specific. The product title, part number and fitment notes should be used together before adding parts to the basket.
Vehicle model
Check Defender or Discovery 2 fitment first, especially on centre sections and rear exhaust parts.

Defender wheelbase
Defender 90 and Defender 110 centre straight pipes are different parts.

Front downpipe type
Match the downpipe to the original front pipe type, including EU2 and de-cat fitment where relevant.

Fitting parts
Old exhaust clamps, gaskets and rubbers are often past saving once the system is disturbed.

Stainless, de-cat and standard TD5 exhaust parts
Individual product pages identify the part type, material and fitment where that information is available. Use the stated vehicle fitment, part number, pipe position and product notes to compare TD5 exhaust components before ordering.
| Part type | How it is used |
|---|---|
| De-cat downpipe | Replaces the catalyst/downpipe section with a freer-flowing front pipe where that setup is being removed or replaced. |
| EU2 downpipe | Standard non-cat front downpipe for TD5 vehicles using the EU2 front pipe setup. |
| Centre straight pipe | Replaces the factory centre silencer with a straight-through pipe for less restriction and a deeper exhaust note. |
| Fitting kit and hardware | Clamps, gaskets, rubbers and small parts for fitting or refreshing the exhaust without relying on tired old hardware. |
