Exhaust · 2026
Toyota Yaris exhaust cost
An exhaust mid-section on a Toyota Yaris typically costs £85–£307 fitted at a UK independent garage, with a full system around £186–£675. Yaris exhaust work is small and cheap — one documented owner replaced all three sections for about £300 — but the model sits adjacent to the UK's catalytic converter theft wave targeting Toyota hybrids, which is why Toyota sells its Catloc guard at cost price.
Emissions hardware
Late diesel Yarises carry a DPF per parts listings. The bigger emissions-hardware story is theft: Toyota hybrid catalytic converters are rich in precious metals because the engine runs less, making them prime UK theft targets — the Prius and Auris were hit hardest, with Yaris thefts also reported. Toyota's response includes the Thatcham-accredited Catloc guard sold at no profit, cost-price replacement bundles, and covert cat marking with police. Newer manifold-integrated cats are far less attractive to thieves.
What's on a Toyota Yaris exhaust?
A short system: manifold with close-coupled cat (later cars integrate it into the manifold as a 'manicat'), front pipe, centre section, rear silencer, single tailpipe throughout. Owners report three-piece replacements around £300 all-in, and aftermarket rear silencers span roughly £43–£121.
Toyota Yaris 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 corrosion advisories and rusted mid/rear sections are the routine reports — with a documented three-piece replacement at about £300, Yaris exhaust work is cheap.
- Cat theft repairs often cost more than the cat: severed oxygen sensors and wiring add roughly £100 per sensor in documented cases.
- Toyota sells its police-approved Catloc guard at cost price and runs a covert cat-marking scheme — worth fitting on older hybrids parked on the street.
- Newer Toyotas integrate the cat into the manifold, which has largely designed the theft problem out.
Good question
Questions Okay gets asked a lot
How much does an exhaust cost for a Toyota Yaris?
+
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.

Should I fit a Catloc to my Toyota Yaris?
+
If it's an older hybrid that parks on the street, it's cheap insurance. The UK's catalytic converter theft wave — roughly 97,000 thefts in under three years at its peak — targeted Toyota hybrids specifically, because their cats stay metal-rich when the engine spends half its life switched off. The Prius and Auris were the prime targets, but Yaris thefts are documented too, and the repair bill goes beyond the cat itself: thieves cut oxygen sensors and wiring on the way through. Toyota sells the Thatcham-accredited Catloc at no profit (fitted, around £200-£240) and offers covert cat marking. Newer Yarises with the manifold-integrated cat are largely theft-proof by design.
How do I know the exhaust is going on a Toyota Yaris?
+
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.
