Freightliner Columbia Performance Exhausts

About Freightliner Columbia Performance Exhaust Systems

Optimize your Freightliner Columbia engine for greater performance with a new aftermarket exhaust system from CARiD. Custom exhausts are specially built to free up engine power that is confined within the system. The Freightliner Columbia stock exhaust is restrictive in nature, in that it does not allow as much exhaust gas to flow out as it should. This is not the case with a custom exhaust system. While the stock exhaust limits the volume of exhaust flow, the custom exhaust system maximizes it, reducing the build-up that hinders the engine from being more efficient. The result is greater power output and increased torque. For the greatest boost in power, torque and efficiency, choose Borla, Flowmaster, Gibson or MagnaFlow Freightliner Columbia cat back exhaust systems. These will yield up to 10% more horsepower. The exact percentage of increase realized will depend on the Columbia engine size and brand of exhaust chosen.

It is a good thing that CARiD stocks a variety of cat back exhaust systems for all 2001 – 2004 Columbia models; at least you are assured of finding an exhaust system that matches your model specifications for optimal gains in power. Power gains aside, a Freightliner Columbia custom exhaust system will improve your mpg by 1- 2%. Since the engine now burns fuel more efficiently, the car will consume less fuel than before. There are also savings to be made when you buy a custom exhaust from CARiD. All our exhaust systems are built for long-term use and lasting performance. You only need to buy and install the exhaust system once and won’t need a replacement in years. And for your assurance and peace of mind, each of our exhaust systems comes with a lifetime or limited lifetime warranty from the manufacturer.

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.
