Your exhaust needs to be in the best possible working condition to ensure safety and functionality.

Exhausts are prone to damage such as external bumps, corrosion and general wear over time. For that reason, we’d recommend that you carry out a physical inspection of the component around every 10,000 miles or year to look for the tell-tale signs of failure.

Signs you need to replace your exhaust

  • Excessive smoke coming from the exhaust pipe.

  • A rattle or knocking noise that sounds like a part has came loose.

  • Visible cracks or holes in the exhaust pipe should prompt you to contact a mechanic ASAP.

  • Rust or splitting on the pipe itself, all exhausts corrode over time but excessive damage should spark concern.

  • Low hanging or dragging exhaust pipe, this may even detach endangering other road users.

  • Reduced fuel efficiency - this may be the result of a number of things including a leak.

  • A hissing noise may be a sign that you have a crack in the exhaust pipe which needs addressing efficiently.

  • Chugging sounds suggest that there is an issue with the flow of gases in the exhaust system. Therefore, there may be a blockage somewhere within it.

  • Roaring noise indicate a problem with your exhaust's silencer, it will be one of the first indications of an issue with your exhaust.
