Peugeot 208 exhaust cost
An exhaust mid-section on a Peugeot 208 typically costs £85–£307 fitted at a UK independent garage, with a full system around £186–£675. The diesel 208's documented DPF trap is unique to PSA: the filter regenerates with help from Eolys additive fluid, and depleted or never-refilled additive — which the car estimates rather than measures — is a well-documented cause of blocked filters.
Emissions hardware
All 208 diesels carry a DPF. Pre-BlueHDi cars use PSA's additive system: a tank of Eolys fluid doses the fuel so the filter can regenerate at small-engine temperatures — and depleted additive, unreliable low-level warnings and skipped refills at services are all documented causes of blocked filters. Post-2018 1.2 PureTech petrols carry a GPF, with clogging on short-trip cars a known issue.
What's on a Peugeot 208 exhaust?
A single-tailpipe supermini system: front pipe/cat (diesels: cat plus DPF assembly), centre section, rear silencer. The rear box hangs on a strap bracket that is itself a common separate replacement part — and aftermarket rear silencers span roughly £46–£136.
Peugeot 208 exhaust replacement cost
A mid-section — the most common failure point — typically costs £85–£307 fitted at a UK independent garage, and a full system around £186–£675. If several sections are corroded, replacing the lot is often cheaper than doing them one MOT at a time. The catalytic converter is a separate, much pricier part.
Key things to know
- Blocked DPFs caused by depleted or never-refilled Eolys additive are the documented PSA-specific failure — the car estimates rather than measures the fluid, and workshops skip the refill at services.
- On any pre-2015 HDi, physically verify the additive level and dosing pump rather than trusting the on-board counter.
- GPF clogging on post-2018 PureTech petrols used for short journeys is documented — the petrol version of the same usage problem.
- The rear silencer's strap bracket fails often enough to be sold as a standalone part — a cheap fix for a hanging box.
Good question
Questions Okay gets asked a lot
How much does an exhaust cost for a Peugeot 208?
+
Expect £85–£307 fitted for the mid-section — the most common failure point on UK cars — and around £186–£675 for a full system (cat-back) at a UK independent garage in 2026. The catalytic converter is a separate, much pricier part and isn't included in these figures. Stainless-steel systems cost more upfront but last three to four times longer than mild steel.

What is Eolys fluid and why does my Peugeot 208 need it?
+
It's the additive that makes the diesel 208's DPF work. Small diesels don't naturally run hot enough to burn soot out of the filter, so PSA doses the fuel with Eolys — a cerium-based fluid from a tank under the car — which lowers the temperature at which regeneration happens. The documented catch: the car estimates rather than measures how much is left, the low-level warning is unreliable on some cars, and garages routinely skip the refill at services. Run out and the filter quietly stops regenerating until it blocks. If you own a pre-BlueHDi 208 (roughly pre-2015), have the additive level and dosing pump physically checked at the next service — it's the cheapest DPF insurance there is.
How do I know the exhaust is going on a Peugeot 208?
+
The classic signs: a deepening, louder engine note (blowing from a corroded section or failed joint), rattling over bumps (broken hangers or internal baffles), and a metallic tinkling on start-up. A sudden loud roar usually means a section has let go completely. At the MOT, a leaking exhaust is a failure and surface corrosion is a common advisory — an advisory on an exhaust section usually becomes a failure within a year, so it's worth pricing the work when the advisory appears rather than waiting.
