The Audi A8 is among the finest full-size luxury sedans in the market. Luxury in a car earns you respect among peers, but a combination of luxury and performance in a car gets you noticed anywhere. You can get this from your A8 if you install a custom exhaust system. A8 custom exhausts are specially engineered to provide greater exhaust flow, beyond what the stock exhaust is capable of. By increasing exhaust gas activity, they keep temperatures down, ensure good supply of fresh air and keep the area surrounding the engine free of spent gases. As a result, the engine is able to generate more power at lower rpm. On average, an A8 custom exhaust will provide 15-20% more horsepower. You will be able to enjoy a greater driving thrill at lower speeds as opposed to experiencing the greatest power surges only at high rpm as you do with the stock exhaust.

Extra benefits of having a custom A8 exhaust are a louder but controlled exhaust note and long-term savings since the exhaust system does not wear out easily. The stock A8 exhaust gives understated exhaust notes that belie the A8 engine power. A custom exhaust on the other hand, gives out an unapologetic roar that denotes a powerful engine. In any case if you prefer your car louder, the A8 stock exhaust is something you will want to replace at the first chance you get. Buy a reliable aftermarket exhaust from CARiD to get the best value for your money. There is a wide range of A8 custom exhausts available, catering to all A8 models. This includes Borla, MagnaFlow, Flowmaster, Gibson, MBRP, Weapon-R, Onki, Zunden and RBP exhausts for both regular wheelbase and long wheelbase A8 models.

      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.
