Is Your 2002-2003 Volvo’s Catalytic Converter Killing Performance?

Got a [2002 Volvo S60 2.4T P2](https://www.aresmortgage.store/collection/volvo-catalytic-converter_1161_79.html) feeling lazy? Or maybe your 2002 V70 or XC70 smells like a sulfur bomb? Chances are that [catalytic converter](https://www.aresmortgage.store/collection/volvo-catalytic-converter_1161_80.html) is clogged or failing. These cars are tanks, but when the cat goes bad, you’ll know—[loss of power](https://www.aresmortgage.store/collection/volvo-catalytic-converter_1161_81.html), check engine lights (P0420/P0430), and that awful rotten egg stench.

The 2002 S80 2.9 and V40 front cat can also get choked up, especially if you’ve been ignoring bad O2 sensors or running cheap gas. And if your 2003 S60 2.4 is struggling, a clogged cat can even cause compression issues—sounds wild, but it happens when exhaust can’t escape.

Replacing the catalytic converter isn’t a fun job (rusty bolts, tight spaces), but aftermarket options exist. Just don’t cheap out—junk converters fail fast. And if you’re doing a full exhaust swap, replace those O2 sensors while you’re in there.

Pro tip: If your cat failed, figure out why (oil burning? misfires?) or the new one will die too.
