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.

      Here's A 'Tip': Exhaust Tips Are An Easy Way To Dress Up Your Tailpipe
      Performance exhaust systems give you improvements in power output, sound levels, and appearance, all in one package. But let's face it: not everyone has the spare change to buy and bolt up one of these kits. So you soldier on with what you have. And that may be a tired-looking exhaust system that is still functional. You've spent all day washing and waxing the vehicle's paint and chrome to perfection, but no degree of elbow grease will make that tailpipe look better.

      Are Headers Worth The Performance Improvement?
      Engines have often been compared to air pumps, because the engine that’s most efficient in terms of economy and power is the one that can get air in and out of its cylinders the easiest. That’s why most performance modifications like conical air filters, cold air intake systems, headers, and cat-back exhaust systems are aimed at making the intake and exhaust systems less restrictive. These parts increase the flow of air into the engine and ease the flow of exhaust gas out of the engine. Among these components, headers may be the most difficult to install. In this article, we’ll discuss what headers do, their different types, and how much performance they can add to your car.

      Are X-pipes and H-pipes Better Than Straight Pipes on Dual Exhaust Systems?
      You may be wondering why so many aftermarket performance exhaust system manufacturers are offering dual exhaust systems connected by "H-pipe" or "X-pipe" sections. After all, aren't two separate pipes, or so-called "true duals", the best for performance? The answer is no, but to understand why we have to examine how a typical internal combustion engine works.

      Power, Sound, Looks | Can I Have It All With a Cat-Back Exhaust System?
      It's an age-old question that many have asked. Will an aftermarket exhaust be worth the expense? While they definitely can be, an important question to ask yourself is do you care more about the deeper sound they’re designed to produce, or the added performance gained from being less restrictive? As car enthusiasts, we’ve become accustomed to associating the sound of a car with its exhaust. After all, doesn’t everyone have a childhood memory or two of a car and the particular sound it made?

      Pickup Truck Cab And Bed Sizes Are Important When Selecting Accessories
      Americans love to have choices. Buying a dress shirt? Decide solid or stripe, short or long sleeve, cotton or poly blend, button or spread collar, regular fit, slim fit, or big & tall. How about a meal at your favorite steak house? Will it be porterhouse, T-bone, or sirloin? Cooked rare, medium-rare, or medium? With baked, mashed, or French fried potatoes? Thirsty for a fancy cup of coffee? Let's not even get started on options that let you end up with a "grande caramel macchiato with 1% low-fat milk, 2 Splendas, and an extra espresso shot".

      Direct Fit vs. Universal Mufflers
      Regardless of whether you're shopping for a simple replacement muffler that delivers original equipment (OE) sound and performance or an upgraded muffler which provides a deeper growl with increased power through freer exhaust flow, you'll see choices between "direct fit" mufflers and "universal" mufflers. In this article, we'll help you understand the differences between these two styles so you can make a more informed purchase.

    Great Sound, Quality Piece
    This muffler sounds exceptional with a nice bassy tone. It is on the loud side, but you can really hear the quality of the motor. It was a perfect fit and was easy to install.
