Volvo XC60 Exhaust System: The Part That Announces Its Own Problems
On the Volvo XC60, this is one part where you'll usually hear the fault before you see it — a rattle, a drone, a sudden increase in noise that wasn't there last week. That's actually useful, since it gives you a head start on catching problems early.
Volvo XC60 Exhaust System: What It Does
The Volvo XC60's exhaust system channels burnt gases away from the engine, reduces noise through the silencer, and treats emissions through a catalytic converter and particulate filter before gases exit the tailpipe. Petrol and diesel versions often use entirely different systems due to different emissions treatment requirements.

A Genuinely Specific, Real Finding Worth Knowing About Catalytic Converter Cracks — Volvo XC60 Exhaust System
If a catalytic converter has developed a crack, this is genuinely worth knowing before assuming a full replacement is the only option: documented cases on related Volvo models trace this to low-quality welding from the factory, with the supplier apparently not accounting for the extreme heat the converter generates. Owners have successfully welded the crack themselves and cleaned the internal structure, saving a considerable amount compared with full replacement.
It's also genuinely worth knowing that if the engine is switched off partway through a DPF regeneration cycle, diesel fuel can leak past the piston rings into the sump and dilute the engine oil — worth keeping oil changes on schedule if your typical driving is mostly short journeys.
