Frequently Asked Questions
Why are catalytic converters so expensive?
Catalytic converters contain precious metals (platinum, palladium, rhodium) that make them expensive to manufacture. OEM units can cost £400-£900+ for parts alone. This also makes them targets for theft.
Will a faulty cat fail my MOT?
Yes. A defective catalytic converter will cause high emissions readings, which is an MOT failure. If your car is producing excessive exhaust smoke or the engine management light is on, get it checked before your MOT.
