Compare Citroen C4 Grand Picasso exhaust fitting quotes from specialist garages

The exhaust system is essential in guiding fumes away from the engine and passengers. It consists of a manifold, flex pipe, catalytic converter and an oxygen or lambda sensor. Unsurprisingly, the biggest problem with car exhausts is that they sometimes develop a leak.

Common warning signs your car's exhaust needs repairing or replacing include: popping sounds, leaking water, rust, unusual smoke, and sounding louder than usual. Anything out of the ordinary may signal a problem, and an exhaust specialist will be able to tell you exactly how to fix it.

It's important to take your car to an exhaust centre as soon as you notice the first signs of trouble; occasionally, exhaust leaks can be dangerous.

Depending on the extent of the leak, a mechanic may be able to carry out an exhaust repair by welding the affected area. If this isn't possible, you'll have to arrange an exhaust replacement.
