Exhaust Pipe buying guide
Why replace this part?
Exhaust pipes route burnt gases from the manifold through the catalytic converter, silencer box, and out of the vehicle. Steel pipes corrode from the inside out due to acidic condensate, particularly on short trips where the exhaust never reaches full operating temperature. A perforated pipe allows toxic carbon monoxide to enter the cabin.
Signs you need a replacement
- Loud exhaust note or hissing
- rattling under the vehicle
- exhaust smell in the cabin
- visible rust holes or blowing joints
- increased exhaust noise that worsens with engine load
- failed MOT on noise or emissions grounds
When to replace
Lifespan varies widely — rear silencer sections typically last 3–6 years on short-trip use; centre and front pipes last longer. Replace sections as they corrode. Stainless steel systems last the lifetime of the vehicle.
