Exhaust · 2026
Honda Civic exhaust cost
An exhaust mid-section on a Honda Civic typically costs £95–£340 fitted at a UK independent garage, with a full system around £209–£748. Two useful Civic facts: the UK 2006–11 diesel has no DPF at all — a genuine ownership advantage — and the model's famous exhaust 'rattle' is usually heat shields or the mid-pipe joint, not a dying silencer.
Emissions hardware
Unusually, UK-spec 2.2 diesel Civics of 2006–11 have no DPF — they avoid regeneration issues entirely. The later 2.2 (2012 on) does carry one, with documented blockages and replacement quotes around £1,000; the 1.6 diesel was designed around its close-coupled DPF, with a documented drive-cycle regeneration procedure (a sustained 37mph+ run of up to 15 minutes) that typically clears warnings.
What's on a Honda Civic exhaust?
Transverse system: downpipe/cat, mid pipe, rear silencer — single tailpipe on mainstream cars, twin or centre exits on sportier trims. The mid-to-downpipe joint and the underfloor heat shields are the documented rattle points, and some Civics use double-walled pipe whose inner and outer walls can resonate against each other.
Honda Civic exhaust replacement cost
A mid-section — the most common failure point — typically costs £95–£340 fitted at a UK independent garage, and a full system around £209–£748. 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
- Before condemning a rattling silencer, check the heat-shield mounting eyelets and the mid-to-downpipe joint — the documented culprits across three Civic generations.
- The UK 2006–11 2.2 diesel has no DPF — a genuine selling point that sidesteps the whole regeneration problem.
- On 1.6 diesel DPF warnings, try the documented drive-cycle regeneration (sustained 37mph+, up to 15 minutes) before workshop intervention — a 20-mile motorway run typically clears it.
- Genuine Honda rear boxes cost several times the aftermarket price (£359 genuine vs £51–£146 pattern for older cars) — which shapes the repair conversation on ageing Civics.
Good question
Questions Okay gets asked a lot
How much does an exhaust cost for a Honda Civic?
+
Expect £95–£340 fitted for the mid-section — the most common failure point on UK cars — and around £209–£748 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.

Does the Honda Civic diesel have DPF problems?
+
It depends entirely on which diesel. The 2006–2011 2.2 i-CTDi sold in the UK has no DPF at all — unusual for its era, and a genuine advantage: no regenerations, no blockages, no filter bills. The 2012-on 2.2 i-DTEC does carry one, with documented blockages on short-journey cars and replacement quotes around £1,000. The 1.6 i-DTEC was designed around its filter — close-coupled to the engine for easy regeneration — and even has a documented self-help procedure: when the warning appears, a sustained run above 37mph for up to 15 minutes usually clears it. So for town-based used buyers, the early 2.2 is quietly the DPF-proof choice.
How do I know the exhaust is going on a Honda Civic?
+
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.
