The Citroën C5 is hailed for its roominess and comfortable ride. But like chili has to be added to the hot sauce recipe to turn it into chili sauce, so should you add a custom exhaust system to the C5 to make it more fun to drive. What manufacturers do not disclose is that in their quest to keep the cost of production down, they go frugal on the stock exhaust material and use cheaper technology to make the exhaust, the end result of which is a stock exhaust that is too small and narrow to effectively support the movement of exhaust flow. Custom C5 exhaust systems are completely different in design. They have larger pipes and are mandrel-bent to produce a smooth, even diameter from header to tailpipe. This enhances exhaust flow and makes the exhaust system more efficient. As a result, the engine operates more efficiently and produces more power. Swap your stock exhaust system for a Borla, Gibson or Flowmaster C5 cat back exhaust system to realize up to 10% extra power and torque.

Onki, Zunden, RBP, Weapon-R and MBRP have a range of custom exhaust headers, tailpipes, mufflers, catalytic converters and tips that you can install in the C5 for enhanced performance. Other than performance and power gains, a custom exhaust system will foster better fuel economy in your C5. This it does by improving fuel efficiency in the engine, and blocking unburned fuel from getting into the exhaust system. When you have a custom exhaust in place, you will enjoy up to 2mpg extra. It may not be apparent that you are saving money when you buy a Citroën C5 custom exhaust, but you are. Here is how: custom exhausts are built for long term use and do not require constant replacing like cheap exhausts do. So you won’t ever have to buy another custom exhaust for your C5 after this one.

      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.

      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.

      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?

      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.

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.
