    Striking an excellent balance between comfort and control on SE suspension, the A3 features a beautifully built cabin and silent driving that is achieved by an excellent exhaust system. Engineers at the Audi company spend a lot of time and efforts to create the mechanism that increases engine performance, saves people inside from the poisonous air, and reduces the level of pollution caused to the environment by your vehicle's exhaust.

    The revolutionary Audi A3 exhaust consists of upgraded components that fulfill the task faster and more effectively. An A3 catalytic converter catalyzes the reaction between carbon monoxide and hydrocarbons to give carbon dioxide and water vapor, which means the level of pollution is reduced to the minimum. Besides, a high-quality muffler will provide you with comfortable silence while you are at the wheel. Last but not least, an Audi manifold will provide you with excellent fuel economy. Of course, all these parts are connected by special hardware such as clamps, hangers, nuts, and so on. Surely, all components wear out and have to be replaced every so often. This is when our collection will come in useful.
