Exhaust system repair
Muffler, catalyst and exhaust pipes - find a specialist, describe the noise and agree the work directly.
The exhaust system - from noise to diagnosis
An exhaust problem rarely goes unnoticed: the car gets loud, something rattles underneath or the engine warning lights up. In this section specialists list muffler repair, catalyst work and sensor replacement.
Where the noise comes from
A roar typically points to a rusted-through or holed element of the exhaust tract, while rattling often means loosened mounts and burnt gaskets. Many such spots are fixed by welding - full replacement is not always needed, and the mechanic will tell you after an inspection on the lift. If an element does need replacing, new and used mufflers are in the parts section.
Catalyst and lambda sensor
Over time the catalyst clogs: power drops, consumption rises, and shaking the body produces a rattle from inside. Every catalyst-related job can be found in this section - repair, installation or removal; each option has its own consequences for emissions and the technical inspection, so ask the mechanic for the full picture before deciding. An engine error in the catalyst zone is often tied not to the catalyst itself but to the lambda sensor - a far simpler part to replace.
When the visit should not wait
Exhaust smell inside the cabin is a danger sign, not a mere discomfort - a check should not be postponed. The same goes for sharply increased noise: driving with an open tract damages neighboring components and risks a roadside stop over the noise. When calling, describe where the sound comes from - front or rear, cold or warmed up - and whether an error shows on the dash.
