    • Performance Parts
      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 Parts
      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 Parts
      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?
    • Performance Parts
      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.

    Supper Cool Sound!
    I bought this for my Mitsubishi and it sounds awesome! It's got a 3.5 l v6 and it makes it sound like its very souped up! And almost like it has a v8 in it. I couldn't be more happy with this product the sound will blow your mind on whatever you choose to put it on whether it be a six cylinder like I put it on or a v8 very much recommend this product if you want a really nearly sound.
