Ford C-Max Exhaust System: OEM Part Number
| Front pipe with catalytic converter (petrol) | Genuinely a different part from the diesel front pipe below — confirm your exact engine code before ordering, and check whether your engine uses a manifold-integrated cat (as confirmed on several Ford EcoBoost units) rather than a separate bolt-in section |
|---|---|
| Front pipe with diesel particulate filter (diesel, where fitted) | A genuinely different assembly from the petrol cat pipe, combining catalytic and particulate filtration in one unit — not sold as two separate parts |
| Centre/intermediate pipe | A genuinely separate section from both the front pipe and rear silencer |
| Rear silencer, front-wheel drive | A genuinely different silencer and mounting arrangement applies versus AWD (where fitted) variants — the underbody routing differs enough that the two aren't interchangeable |
| Rear silencer, AWD (where fitted) | A genuinely different silencer and mounting from the front-wheel-drive version above, to clear the rear differential and driveshaft routing |
| higher-output rear silencer | A genuinely different, larger-bore twin-exit system from the standard rear silencer — not a like-for-like swap |
A Genuinely Major, Current Recall Worth Checking If You Have a Diesel — Ford C-Max Exhaust System
This is worth checking directly against your registration if you own a diesel C-Max: Ford has confirmed a major, current recall (reference 24E06, part of the broader KBA 14555R campaign) addressing a design-related weakness in the Diesel Particulate Filter material that can develop hairline cracks over its service life. This isn't a minor administrative recall — a cracked DPF lets unburned particulate matter bypass the filter, which can cause a failed MOT emissions test and potential Clean Air Zone compliance issues. The recall covers over 1.2 million Ford diesel vehicles worldwide across nearly the entire range — including the C-Max — built between 2014 and 2023.
Ford C-Max Exhaust System: The Part That Announces Its Own Problems
Where a lot of Ford C-Max parts fail silently until you spot something visually wrong, this one tends to make noise first — a rattle, a drone, an audible change that wasn't there recently. That's a useful early-warning system if you're paying attention.
Ford C-Max Exhaust System: What It Does
Away from the engine, through the silencer, and often through a catalytic converter and particulate filter before reaching the tailpipe — that's the Ford C-Max's exhaust job in three steps. Petrol and diesel versions frequently need different systems entirely, since their emissions treatment isn't the same.
