Checks On Car Exhaust Systems - Catalytic Converters

We locate the car's exhaust problem quickly and fix it..

How do you know if your exhaust needs attention?

Any of the following symptoms may indicate a fault with your vehicles exhaust system and should be addressed to avoid further and possibly more expensive damage.

  • A noises from beneath your car (clunking or rattling).
  • A “hissing" sound may indicate a crack in the exhaust manifold, pipe or a leaking gasket.
  • A "knocking" noise may indicate a blockage in the exhaust system.
  • Poor and sometimes erratic performance.
  • High or inconsistent revving engine.
  • Unusually high fuel consumption.

The silencer box is the furthest away from the engine and is the most likely to be corroded by acidic moisture and require attention at the outset of the inspection. Because these parts remain relatively cold and give exhaust gases a chance to condense and form pools of corrosive acid inside the system.

You will know that you have a problem with your silencer because your exhaust starts making a roaring sound.

Your exhaust is held in place with hangers, brackets and clamps beneath the car. Rattling sounds coming from underneath the car could mean that the exhaust system has become misaligned or that one of the support brackets or components has become loose or damaged. Corroded, fractured or missing hangers or brackets can cause extra stress, which can also lead to premature exhaust failure. However early remedy of these relatively minor problems can save on early expensive replacement costs.

Problems with the exhaust can be identified with a visual check. External rust may not be as serious as it first appears as it may only be on the surface, but cracks in the pipe or jagged holes around seams and joins between pipes can be signs of bigger problems.

Full replacement or replacement components?

Exhaust systems are constructed from a number of units fitted together. It is possible to replace only the failed components (perhaps a holed silencer) however, failure of one of the components may have damaged another component thereby requiring its replacement as well. One problem can often produce a knock on effect.

We have access to the full range of original and approved OEM components for even the most complex exhaust systems and can advise the customer on the best option.

Whatever the failure, at Portsmouth Motor Company Ltd we will advise on the best possible solution to suit your requirements and budget. Please contact us for advice and estimates.
