Rear silencer for your car

BUY AND REPAIR THE RIGHT REAR SILENCER AT Q-PARTS24

The repair of a rear silencer with the welding machine is usually successful but does not last long. Because the damage caused by rust and stress cracks is usually too far advanced, if the damage to the exhaust is noticeable, a new exhaust is the best and most sustainable solution here. Don't ignore the damage, because a broken rear silencer leads to significant noise pollution and reduced engine performance. To replace the muffler, the car must be driven over a pit or onto a lift. Allow the exhaust, which has become hot during operation, to cool down to a safe temperature. Now check the entire exhaust system and other muffler components for additional rust spots and thus prevent further damage, because defects of this type often do not only occur in the muffler. Now use the appropriate exhaust tool to unscrew the defective or rusted-through rear silencer from the car. If the screws are stuck due to rust, you can treat them with a special rust remover. Now you can attach the new rear silencer including the new exhaust gasket and new exhaust screws to the car. The work takes about one to two hours and is best done with two people.

FUNCTIONS OF A CAR SILENCER

Part of the exhaust system and various mufflers, the rear muffler is one of the final components that exhaust gases pass through before being blown out. The rear silencer is located at the rear of your car and is connected to the front silencer via a pipe on one side and to the tailpipe on the other side. Depending on the design, the muffler has a round, square or flat shape, with the two entrances being at opposite ends of the component. Our rear silencer range includes various spare parts with different diameters for the inlet and outlet.

Rear mufflers are divided into reflection mufflers and absorption mufflers. With reflective mufflers, the exhaust gases are sent to several chambers, where they are reflected, losing power in the process. Absorption mufflers contain porous materials such as rock wool or glass wool, which slow down the exhaust gases and absorb the sound. In both cases, the sound pressure of the exiting exhaust gases, which has already been lowered by the pre-silencer, is further reduced in order to avoid noise pollution. A variant of the rear silencers are the so-called sports silencers. In addition to reducing the volume to a pleasant level, the focus here is on the pithy sound. The maximum sound pressure depends on the power-to-mass ratio of the vehicle and is around 70 decibels.

DETECT DAMAGE TO THE REAR SILENCER IN TIME

The constant vibrations, corrosion caused by road salt and other environmental influences as well as mechanical damage and frequent heating and cooling can cause cracks and holes in the rear muffler, like all other muffler parts. Even a layman will immediately recognize damage to the rear silencer, because the exhaust noise changes noticeably even with small gaps and rusted-through spots. In addition to an increased volume and a change in the sound pattern, there can also be audible rattling, for example if a metal part has fallen into the rear silencer and is now bouncing around in it due to vibrations. An exact diagnosis is best made by visual inspection. Most of the time, the rusted through areas, cracks and holes are easy to see even without a lifting platform.
