Citroen C5 Performance Exhaust Systems

About Citroen C5 Performance Exhaust Systems

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.

    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...
    It has been a battle of the ages to make exhaust sound like it should. Having less bends or turns will not only improve the sound but also performance. A custom exhaust is always an option for the race inspired and spirited weekend warriors. Our manufactures offer everything needed to build a custom exhaust to your preference.
    Headers are installed because the stock exhaust manifolds usually flow poorly. An exhaust header has individual tubes for each exhaust port, allowing each exhaust pulse to flow unobstructed from the cylinder head. The tubes on headers are usually larger in diameter than the runners on an exhaust manifold and the tubes are mandrel bent for gradual radius bends.
