Used Peugeot 108 Exhaust System

The Peugeot 108 was launched in 2014 and ran through to 2021 as a single generation, but the year of the donor car still matters because exhaust systems follow the engine code and emissions era rather than the model year alone. A part from a 2014 car on the same engine code and fuel type as your 2017 car is a reasonable starting point, but you should confirm with the breaker that both registrations share the same engine code and emissions spec before buying. Never assume fitment purely on model-year proximity.

No — petrol and diesel exhaust systems are completely different in layout, diameter, and emissions equipment, so they are not interchangeable. The 108 was sold in the UK predominantly as a petrol, so always confirm the fuel type of the donor car with the breaker matches yours exactly. Fitting the wrong system would affect emissions, performance, and MOT compliance.

Trim level does not affect exhaust fitment on the Peugeot 108 — Active, Allure, and Roland Garros all share the same exhaust routing on a given engine code and fuel type. What you may find is that the condition or finish of a part pulled from a higher-spec car is no different mechanically, so do not pay a premium purely on trim grounds. Match on engine code, fuel, and registration year instead.

Yes — emissions era is one of the most important matching factors for an exhaust system, because the catalytic converter and associated components are engineered to the Euro standard the vehicle was built to. Fitting a system from the wrong emissions era could cause an MOT failure or poor running. Because the specifics of which catalytic converter or DPF components interchange across Euro 5 and Euro 6 builds are complex, you should confirm this detail directly with the breaker against your exact registration.

The engine code and emissions standard of the later car would need to match your 2015 vehicle exactly, and a 2019–2020 car is more likely to be on a later emissions calibration than a 2015 example, which could mean differences in the catalytic converter or pipe specifications. The overall generation ran 2014–2021 without a major structural change, but that does not mean all exhausts within that span are interchangeable. Route this specific cross-year question to the breaker, quoting both registrations, so they can verify compatibility before you commit.

The engine code is the single most reliable way for a breaker to match an exhaust to your car, alongside the fuel type and registration year. You can find the engine code on your V5C logbook, on a sticker under the bonnet, or by asking a dealer or mechanic to read it. Providing your full registration as well allows the breaker to cross-reference their stock and flag any emissions-era differences that could affect fitment.
