Buy a new custom exhaust system for the BMW X3 and enjoy the difference in throttle response and power boost it brings. Visit CARiD for the widest variety of X3 custom exhaust systems, mufflers, headers, catalytic converters, pipes and tips. Their X3 exhausts are specially built to optimize exhaust flow, eliminating the build-up of spent gases which inhibits the proper functioning of the engine. With a custom exhaust, your engine will optimize all its power, generating an extra 5hp at the very least. You will also experience greater pull when handling a challenging road section due to the increased torque. CARiD has a number of Borla, MagnaFlow and AFE cat back systems that you can opt for. These are best used when you want to replace the entire stock exhaust. If you only want to replace bits of the stock exhaust, go for catalytic converters, exhaust down pipes, headers or mufflers from AFE, Flowmaster, Weapon-R or Gibson. They are compatible with the stock exhaust and will be an exact fit.

Another great advantage in getting an aftermarket X3 exhaust system is the long-term savings you gain. Custom exhausts are built to last and do not wear out as easily. Most of the exhaust systems at CARiD are made from hardy stainless steel and aluminized steel. They last for years and don’t need to be replaced within a few years. Additionally, their performance remains top form: you will be enjoying the same results from your X3 custom exhaust even after 5 years or more. You cannot get such enormous value for money from the stock exhaust, which wears out and drags engine performance down in just a couple of years. You will also love the rumble a custom exhaust adds to your X3 engine. Powerful yet controlled, it certainly makes driving the X3 even more enjoyable.

      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.
    • Performance Exhaust Systems
      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.
