Freightliner FLD Performance Exhaust Systems

About Freightliner FLD Performance Exhaust Systems

Improve the performance of your Freightliner FLD engine with a new custom exhaust system from CARiD. Designed to fit into the engine perfectly, each of our FLD custom exhaust systems boost engine efficiency, releasing more horsepower and increasing torque by a considerable amount. Freightliner FLD custom exhaust systems works by increasing exhaust flow and reducing backpressure, which is responsible for the loss of engine power. When the backpressure goes down, the volume of exhaust flow increases, leaving the engine free to efficiently take in the fresh air-fuel mixture it needs to generate power. The results are more horsepower, faster accelerate and greater pulling power. We stock performance exhaust systems for all Freightliner FLD trucks released between 1988 and 2004. There are tons of direct replacement exhaust systems and performance exhaust components to choose from, all manufactured by leading brands such as Borla, MagnaFlow, Flowmaster, Gibson, MBRP, RBP, Zunden , Onki and Weapon-R.

Replacing the entire stock exhaust will give you the greatest overall efficiency. Complete exhaust systems are ideal for this. To improve a particular area between horsepower/torque and sound, go for a pair of headers, catalytic converters, mufflers, exhaust pipes, tips or exhaust kits from any of the listed brands. Your choice will b determined by what you want to achieve. We have tens of each component to choose from. Choose the exhaust system that corresponds to your car’s specifications, as this will determine just how effective the custom exhaust becomes. One other benefit a Freightliner FLD custom exhaust system gives is improved sound. You will enjoy the new exhaust sound from your truck. Where the stock exhaust note may have gotten shrilly with time, a custom exhaust will add a touch of the throaty growl that denotes the power within a truck.

    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.
