Used Fiat 500X Exhaust System

The Fiat 500X was introduced in 2015 and received a facelift in 2018, so a 2016 system comes from the pre-facelift generation and a 2019 system from the post-facelift generation — these sit either side of a known production boundary. Whether a specific exhaust crosses that boundary depends on whether your engine code and emissions standard match, and that is strong confirm-with-breaker territory. Always give the breaker your registration and ask them to cross-reference the engine code before buying.

Yes, petrol and diesel 500X exhausts are not interchangeable — the diesel system is built around a Diesel Particulate Filter (DPF) that the petrol system does not have, and the pipe routing and mounting points differ accordingly. Fitting a diesel exhaust to a petrol car or vice versa will not work correctly and could cause an MOT failure. Always confirm fuel type with the breaker when requesting a quote.

Trim level — whether Pop Star, Cross, Cross Plus, or Sport — does not determine exhaust fitment on the 500X; what matters is the engine code and emissions standard. You may find minor cosmetic differences such as the style of the tailpipe finisher, so check with the breaker whether any visible trim pieces are included or need to be swapped over. The core pipework and mounting positions are shared across trims for the same engine and emissions era.

For the 500X you should identify your exact engine code from your V5C or by asking the breaker to check against your registration, as Fiat fitted several units including 1.4-litre and 1.6-litre petrol engines alongside 1.3-litre and 1.6-litre diesel units across the range. Exhausts are engineered to specific engines, so even within the same fuel type a system from one engine will typically not fit another. Quote your registration and engine code to the breaker to get the right match.

The 2018 facelift broadly aligned with tightening Euro 6 emissions requirements, and fitting an exhaust from the wrong emissions era — particularly one with a different catalyst or DPF specification — risks an MOT emissions failure even if it physically mounts up. Whether a specific pre-2018 part is compatible with a post-2018 registration is something you must confirm with the breaker against your exact registration and engine code, as interchange specifics around catalytic converters and DPFs are not straightforward. Do not assume visual similarity means the part will meet the emissions standard your car was registered under.

Individual sections — such as the centre pipe, rear silencer, or back box — can often be sourced separately, and the breaker will usually sell them this way. However, if your front pipe or catalytic converter is from a different engine generation or emissions era, mixing sections can create fitment or emissions problems. Confirm with the breaker which section you need and ensure it corresponds to your exact engine code and emissions specification.
