Peugeot 108 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 |
|---|---|

| Centre/intermediate pipe | A genuinely separate section from both the front pipe and rear silencer, confirmed shared across the wider PSA Group range in many cases |
| Rear silencer | Confirm your exact engine and trim, since PSA Group used multiple distinct rear silencer references across most model generations |
A Genuine Warning Worth Knowing: DPF Deletion Is Illegal and Can Be Genuinely Dangerous — Peugeot 108 Exhaust System
If you're facing a costly DPF or EGR repair and have come across "DPF deletion" as a cheaper alternative, this is worth understanding properly before considering it: removing or gutting the DPF filter is illegal in the UK and will cause an automatic MOT failure once detected — testers now specifically check for this. Beyond the legal risk, it's worth knowing about a genuinely concerning real case: one documented DPF deletion also involved the EGR valve being blocked to allow only fresh air intake, after which the owner began smelling exhaust gas inside the cabin while driving — a real, potential carbon monoxide exposure risk, not just an unpleasant smell. Whatever the cost pressure, a genuine repair rather than a deletion is worth pursuing given both the legal exposure and this kind of real safety risk.
A blocked DPF is overwhelmingly a short-journey problem — sustained motorway driving at around 60mph for at least 15 minutes allows a mildly blocked filter to complete a regeneration cycle and clear the fault naturally. If an "anti-pollution fault" message appears alongside a sudden loss of power, the car has entered limp mode as a protective measure — worth addressing promptly rather than continuing to drive on it.
Peugeot 108 Exhaust System: The Part That Announces Its Own Problems
On the Peugeot 108, this is one of the few parts where your ears will catch a problem before your eyes do — a new rattle, a drone, noise that simply wasn't there a week ago. That's a genuine advantage, since it gives you an early warning most other faults don't offer.
Peugeot 108 Exhaust System: What It Does
On the Peugeot 108, burnt gases leave the engine through the exhaust system, which quiets them via the silencer and treats emissions through a catalytic converter and particulate filter before anything exits the tailpipe. Petrol and diesel versions frequently use entirely different systems, since their emissions treatment needs aren't the same.
