Buick Century Performance Exhaust Systems

Improve the performance of your Buick Century with a new custom exhaust. Designed to fit in with the car’s engine, Century custom exhausts will boost engine efficiency, delivering more horsepower and raising torque by a considerable percentage. For the best quality of exhaust systems, buy yours from CARiD. They have custom exhausts for all Buick Century models released between 1977 and 2005. The Century custom exhaust system works by reducing backpressure, which is responsible for sapping engine power. When the level of backpressure in the exhaust system is brought down, the volume of exhaust flow increases, leaving the engine free to do what it does best: generate power. The resulting effect is more horsepower, the ability to drive faster, accelerate faster and tackle challenging roads with ease.

Replacing the entire stock exhaust will reward you with greater overall efficiency, and MagnaFlow, Borla and Flowmaster cat back systems for the Century will give you this. If you only want to improve on one particular area, say horsepower, torque or sound, opt for any of the headers, catalytic converters, exhaust pipes, mufflers and exhaust tips from Borla, Gibson, Weapon-R, Onki, RBP, Flowmaster, Zunden or MBRP. Be sure to choose the exhaust system that matches your car’s specifications, taking into account all the modifications you may have already done on the car, as this will affect the overall impact of the custom exhaust. One extra benefit of getting a custom Century exhaust is improved sound. An old exhaust system, which in your case may be the Century’s stock exhaust or a cheap replacement you or the previous owner had installed, sounds groggy with time. A custom exhaust will restore the deep exhaust note that reassures of a powerful engine.

    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.
