Unlike the given performance stats from Audi official and car reviewers, the A6 has the capacity to go beyond its indicated maximum power. This applies to all A6 models and can be accomplished by simply installing a high performance exhaust system in place of the stock exhaust. In the 177 hp diesel option, a custom exhaust has the capacity to increase horsepower to as high as 200hp. Turbocharged versions of the A6 benefit not just from massive power gains but also a wider power band, meaning you will be able to enjoy more power from the A6 single/twin turbo engines at much lower rpm levels than before when you install a custom exhaust system. For the best in A6 custom exhausts, check out CARiD’s wide offering. It includes customized exhaust systems from leading manufacturers Borla, MagnaFlow, Flowmaster, Gibson, Zunden, Weapon-R, MBRP, RPB and Onki. CARiD stocks different exhaust systems for all A6 models from these brands. Whether you are looking for the right exhaust system for your upgraded 2002 A6 or the newest 2013 A6, you will find it at CARiD.

Beyond the indicated power gains and performance enhancement, your A6 will develop a new sound, which is more pleasant and richer. On acceleration, the custom A6 exhaust gives a rich growl commonly heard in high performance sports cars. The exhaust blocks all engine vibrations and unwanted noise such that even at high rpm, the car gives a consistent, non-disruptive tone, something the A6 stock exhaust does not offer. Another important benefit an aftermarket A6 exhaust gives is higher mpg. By releasing more power at lower rpm, you will not need to accelerate as often as before to hit maximum power, and you can cover more miles per gallon.

      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?

      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?

      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.
