Used Mercedes-Benz CLA Exhaust System

The Mercedes-Benz CLA (C117) ran from 2013 to 2019, with a facelift in 2016, and the second generation (C118) arrived for 2019 onwards — these two generations use different platforms and exhaust systems, so a part from a C117 will not cross over to a C118. Within the C117 generation, the engine code and emissions standard (Euro 5 pre-facelift, Euro 6 from around the 2016 facelift onwards) matter far more than the model year alone, so always match on engine code first. Confirm exact fitment with the breaker against your registration before buying.

The 2016 facelift of the C117 CLA brought Euro 6 emissions compliance across the range, which can mean differences in the exhaust system — particularly around catalytic converter and DPF configuration — compared with the Euro 5 pre-facelift cars. The pipe routing and mountings may look similar, making a cross-era swap tempting, but fitting a Euro 5 system to a Euro 6 car (or vice versa) risks an MOT failure. Name the boundary to your breaker (pre-facelift 2013–2016 vs post-facelift 2016–2019) and ask them to check your specific engine code before agreeing a sale.

For the standard exhaust system, trim level — whether Sport, AMG Line, or Urban — does not affect fitment; what matters is the engine code and emissions era. However, AMG Line models may have different rear bumper apertures or exhaust tip finishers styled to suit twin or quad outlets, so a system from a Sport car may fit mechanically but look mismatched at the back. If cosmetic appearance matters to you, mention your trim to the breaker so they can supply tips or finishers that suit your bumper cut-out.

The CLA 200d and CLA 220d are diesel engines and, while they share the same OM651 engine family in the C117 generation, differences in tune and exhaust gas management mean the systems are not always a straight swap. DPF and catalyst configuration in particular is strong confirm-with-breaker territory — do not assume interchangeability based on the engine family alone. Give the breaker both your engine code and your registration so they can check the exact part numbers before you commit.

No — petrol and diesel exhaust systems are not interchangeable on the CLA; diesel cars carry a diesel particulate filter (DPF) as part of the system, which petrol variants do not use in the same way. The pipe diameter, mounting positions, and aftertreatment components differ between fuels. Always specify petrol or diesel (and your engine code) when requesting a quote from a breaker.

Give them your full registration number, which lets them confirm the engine code, fuel type, and emissions standard (Euro 5 or Euro 6) — all of which directly affect which exhaust fits. Also clarify which section you need: front pipe, centre section, or rear box, as breakers often sell these separately from dismantled cars. If your car has the AMG Line trim with a specific bumper style, mention that too so the exit tips and finishers match your rear valance.
