New exhaust & emissions
Cats, DPFs, lambda sensors, EGR valves and centre/back boxes.
Emissions parts: establish the component and the cause
An EGR offer may cover the valve alone or an assembly; a filter or sensor offer may omit its fittings. Record the existing identifier and component position, then compare the included items. Ask your repairer to establish the cause of the fault before deciding that replacement is the right next step.
Understand OEM, aftermarket and used-part labelsExhaust & Emissions questions
Are the quoted cats and DPFs type-approved for UK MOT?
The named supplier’s written offer should confirm the applicable type approval or E-mark for the quoted component. A component alone cannot guarantee an MOT result because fitment and the wider emissions system also matter.
How fast can you deliver?
Delivery timing depends on the part, destination and current availability. Review the estimated dispatch window and delivery method in the named supplier’s written offer before ordering.
What if I find it cheaper elsewhere?
Compare like-for-like quotes using the brand, specification, included items, delivery charge and warranty terms as well as the headline price.
Do the parts come with a warranty?
Warranty periods, fitting requirements and exclusions vary by part. The named supplier’s written offer and order documents will state the applicable terms before you order.
