Ford Ka / Ka+ exhaust cost
An exhaust mid-section on a Ford Ka / Ka+ typically costs £85–£307 fitted at a UK independent garage, with a full system around £186–£675. Small, simple, cheap systems — a fitted Ka back box is advertised under £200 at UK exhaust chains. On the rust-prone original Ka, the honest risk isn't the exhaust: it's the corroded hangers, fasteners and metal around it.
Emissions hardware
The Mk1 had no diesel. The Mk2's 1.3 TDCi came with or without a DPF depending on variant — check per car. No petrol Ka carries a GPF.
What's on a Ford Ka / Ka+ exhaust?
Short, simple systems on every generation: cat up front, then an inexpensive bolt-on back box — pattern rear boxes for the Mk2 list around £64, and UK exhaust fitters advertise a fitted rear box for the 1.2 at £166–£193 including labour and VAT. The Fiat-500-based Mk2 shares parts with the 500, so cross-references widen the options.
Ford Ka / Ka+ 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
- Exhaust work on a Ka is about as cheap as car repair gets — small system, bolt-on back box, with fitted prices under £200 advertised by UK exhaust fitters.
- On the corrosion-famous Mk1, the fasteners, hangers and surrounding metal may be in worse shape than the exhaust — sensible quotes carry contingency.
- The Mk2 shares its platform and many exhaust parts with the Fiat 500 — worth checking cross-references when sourcing parts.
- No documented flexi-failure epidemic on any Ka — standard small-car exhaust wear applies.
Good question
Questions Okay gets asked a lot
How much does an exhaust cost for a Ford Ka / Ka+?
+
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.

How much is a new back box for a Ford Ka?
+
It's one of the cheapest exhaust jobs in the UK. Pattern rear boxes for the Mk2 (2008–16) list around £64 in parts, and UK exhaust fitters advertise the fitted job — parts, labour and VAT — at under £200. The Mk1's system is simpler still. The only caveat on an older Ka is what the fitter finds around the exhaust: the original Ka's legendary corrosion means seized clamps, rotten hangers and crusty metal can add time. If your Ka is otherwise sound, though, a blowing back box is a same-day, small-money fix.
How do I know the exhaust is going on a Ford Ka / Ka+?
+
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.
