What exhausts involves
Exhausts live a hard life — heat cycling, road salt and water all attack them from both sides. Most failures start as a pinhole or a corroded joint that turns into the unmistakable blowing sound. Beyond the noise, a leaking exhaust can let fumes in, upset the engine's sensors and hurt fuel economy, so it's worth fixing promptly.
Signs of an exhaust problem
- A deep droning, roaring or blowing noise, especially under acceleration
- A rattle from underneath, often a loose heat shield or a broken hanger
- Visible rust, holes or soot marks along the pipework or at a joint
- A smell of exhaust fumes inside the car
- The exhaust hanging low or knocking against the underside
- Noticeably worse fuel economy or a lit engine management light
What we do at the workshop
- 1Put the car on the lift and inspect the full system from manifold to tailpipe
- 2Locate the leak precisely — it's often a joint or a corroded section, not the whole system
- 3Replace mountings, hangers, clamps, gaskets or heat shields where those are the problem
- 4Supply and fit replacement exhaust sections, back boxes and centre sections
- 5Check for exhaust-related noises that are actually something else, so you don't pay for the wrong part
- 6Run the engine and re-check for leaks before the car goes back to you

How long it takes
A back box or single section replacement typically takes around an hour. Seized fixings or a larger system can take longer.
