      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.
    • Performance Exhaust Systems
      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".
    • Replacement Exhaust Parts
      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.
