Cat converters & DPF

Exhaust tailpipe emitting vapour

Catalytic converters and diesel particulate filters (DPFs) keep emissions in check. When they fail or block up, your car can lose power and throw warning lights. We diagnose the problem and get it sorted.

What we do

  • Catalytic converter replacement
  • DPF-back exhaust work
  • Fitting of replacement cats and DPF housings
  • Leak repairs around sensors and joints
  • Advice on whether the issue is the part or something upstream

Signs it’s time to see us

  • Check-engine or DPF warning light
  • Loss of power or limp mode
  • Rotten-egg smell from the exhaust
  • Rattling from the converter
  • Failed emissions or roadworthy check

Removing a catalytic converter or DPF from a road vehicle is illegal in Australia, so the focus is on getting yours working properly again.
