    Whether you are replacing the exhaust on your A3 to change the look of your Audi or because you are looking to improve the car’s performance, extra power is one of the benefits you will tap into when you buy a high performance custom exhaust. An aftermarket exhaust system can boost your A3 engine’s power by as much as 23hp, depending on the specifications you go for. For the widest variety of A3 exhausts, shop at CARiD. The store stocks hundreds of complete exhaust systems and parts for all Audi A3 editions, right from 2003 models to 2013 models. For maximum power gains, opt for the Audi A3 Borla exhaust system. It is designed to increase exhaust gas movement - pushing more air in and out of the engine - and has the capacity to boost horsepower by 15%. The MagnaFlow exhaust system for 2006-2012 A3 models gives between 3 and 23hp depending on model and car specifications, and torque gains of 38 Nm.

    An additional benefit of installing a custom A3 exhaust is the deeper engine note it gives your car. Not only does your car tone get richer and more pleasant, any vibrations the older sock exhaust may have been echoing will be absent. Custom mufflers in all exhausts sold at CARiD are infused with impenetrable sound-proofing to block noise and vibrations, leaving a smooth, even-toned growl that gets richer with increase in speed. They are also good value for money with their long life and high performance abilities. In addition to the wide range of A3 exhaust system options from Borla, MagnaFlow, Flowmaster, Gibson, Zunden, Waepon-R or MBRP it gives, CARiD also offers exceptional customer and after-sales support.
