If your car sounds louder than usual or you hear an unusually loud roaring noise when you start the engine, the problem could be with the exhaust system. Other symptoms like smoke in the cabin, rattling sound, excessive vibrations, or loss of power can also occur.
If you experience any of the symptoms, get the exhaust system checked and repaired promptly. However, You can avoid any kind of problems with your exhaust system by installing a performance exhaust system like the Holden Ve-VF collection that will not only make your car look cool, but will also help it to run more efficiently.
Exhaust problems must be fixed as a priority because there is a risk of exhaust gases entering the cabin. Exhaust problems also get progressively worse and it makes sense and costs less to fix the problem in the early stages.
Exhaust System Basics
The purpose of the exhaust system is to limit emissions, noise, and vibrations, and safely release combustion gases. It consists of a chain of components on the underside of your car. It runs almost the length of the vehicle starting from the engine to the rear exhaust pipe.
The start of the chain is the manifold, which collects exhaust fumes from the engine. From there, the gases go through a pre-catalytic converter and then the main catalytic converter where harmful hydrocarbons are removed.
Silencers (mufflers) in the exhaust system reduce the noise created by the gases as they are expelled from the engine. Damage to the exhaust system can increase noise, vibrations, and emissions besides allowing dangerous combustion gases into the cabin. A malfunctioning exhaust can also reduce engine performance.
