Replace the stock exhaust system on your Ford Focus with a brand new custom exhaust system and see what a difference it makes in your engine’s performance. Very different from the stock exhaust system in design, the custom exhaust system is built to maximize exhaust flow, thus minimizing backpressure within the system and freeing power that is trapped within the engine. CARiD brings you the finest range of performance exhaust systems for the Ford Focus. Take your pick from the tried and tested Borla, MagnaFlow or Flowmaster, all of whom have a series of Ford Focus cat back exhaust systems. With any of their exhausts, you can anticipate power gains of up to 10%. Also available are performance catalytic converters, mufflers,headers and tips from Gibson, Weapon-R, Oki and RBP. You can use these alongside the exhaust system for an additional 10-20hp.

If the effects of a custom exhaust system appear to be too good, it’s because they are. The performance boost won’t just be in horsepower alone, but also in important determinants such as torque and throttle response. With greater torque, you will maneuver your way through tough roads with ease and enjoy greater punch from the Focus. You will also have more power at your disposal on lower rpm than before, which makes driving at low speeds more exciting. Custom Ford Focus exhaust systems boost the engine’s fuel efficiency, boosting your gas mileage by as much as 3mpg which is good for your finances. The Ford Focus custom exhaust sound has no equal. Throaty and deep, it leaves no doubt about the power of the engine beneath your hood.

      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? 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.
