Ever wondered how to get your Freightliner FL-Series truck rearing to go like before? That’s something you can achieve with the help of a brand new custom exhaust system from CARiD. High quality and superbly engineered, our exhaust systems are designed to maximize exhaust flow in order to boost the performance of the FL-Series engine. When a stock exhaust system is in use, the car spends huge amounts of power diffusing exhaust gases which cannot be expelled smoothly due to the restrictive design of the stock exhaust system. When you replace the stock exhaust system with a custom exhaust system, exhaust gas flows efficiently and the power that was previously spent getting rid of it is now channeled to the motor. CARiD offers a range of Freightliner FL-Series custom exhaust systems. Borla, MagnaFlow, Flowmaster, Weapon-R, Zunden, Onki, MBRP and Gibson have a range of cat back exhaust systems and performance exhaust kits and components for the FL-Series that you can choose from.

Any of our direct replacement exhaust systems will give between 5-10% extra horsepower and an equal amount of torque. Combining it with any of the custom headers, mufflers, catalytic converters, tailpipes, and exhaust kits we have available will give you an additional 10-20hp. Cheap OEM exhausts will not make any difference in engine power and torque. That leaves performance exhaust systems as the only type of exhausts that will increase the power output of your engine. A new FL-Series exhaust system will improve mileage by 1 or 2%, meaning you will now drive longer distances on the same amount of fuel. You also get to enjoy better exhaust sound. Freightliner FL-Series custom exhausts have a remarkably deep and throaty engine note which sounds much better than the stock exhaust note.

      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?

      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.
