Pump some life into your Ford Flex engine with a new custom exhaust system. Over time, the Flex performance goes down and is made worse by a deteriorating stock exhaust system. A custom exhaust system does restore its performance to a significantly higher level. Buy the best quality exhaust system from CARiD and you won’t have to worry about what effect it will have on your Flex engine. The exhaust will also improve horsepower and torque so that your car has greater towing power and faster throttle response. We have a number of exhaust systems custom designed for the Ford Flex at CARiD. For the ultimate surge in power and torque, consider buying the MagnaFlow Ford Flex Cat Back System or CGS Cat Back Exhaust System for the Ford Flex. Both will give you between 5% and 10% more power. You can supplement the exhaust system with performance headers and mufflers from Gibson or Flowmaster to enjoy an additional 10-20hp.

Ford Flex custom exhaust systems are built for tough driving and wear really well. Buying one of our exhaust systems ensures that you do not go back to the shop for a replacement exhaust system, and that your performance needs are met over the long term. All our custom exhausts are designed to last and do not break down or dip in performance as quickly as stock exhaust systems do. With their guaranteed durability and lifetime warranties for back-up, they are the perfect choice for anyone who wants to make long-term savings. Finally, you won’t get enough of the new Ford Flex custom exhaust sound. All Flex custom exhausts system at CARiD have moderate to aggressive sound levels, which are more powerful than the Ford Flex stock exhaust note.

    Guides & Articles

    • 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.
