Buick Roadmaster Performance Exhaust Systems

About Buick Roadmaster Performance Exhaust Systems

The Buick Roadmaster was built to rule the roads. If you own one of these cars you know that for sure. But like a swing is given a push to begin its oscillation, you can enjoy a more satisfying ride from your Roadmaster with a custom exhaust system from CARiD. Even the most well-maintained stock exhaust system gets worn out over time. Unlike custom exhaust systems, Roadmaster stock and OEM exhausts are made from lower quality materials that cannot put up with long term use. Additionally, their volumetric exhaust flow is lower than what a custom exhaust can handle. Replacing the exhaust system with a custom exhaust is the right way to improve engine performance and see immense gains in power and torque. Get an extra 5-10% of horsepower from the Flowmaster, MagnaFlow, Borla, Gibson or Onki Roadmaster exhaust system. These cat back and axle-back systems replace the entire exhaust system, giving your engine room to breathe and eliminating the build-up of pressure.

As well as power and torque increase and better engine efficiency, a custom exhaust system will make your car sound better. Each custom Roadmaster exhaust is designed to give a specific engine note, from the low and throaty to the high and powerful. Let the staff at CARiD know the exact sound you would like to get from your Roadmaster engine and they will suggest the best custom exhaust for you. A performance custom exhaust from the shop will also save you money as it is built to give lasting durability. Replacing the exhaust system every now and then is costly, which is why these aftermarket exhausts were designed. They provide instant power and engine sound solutions at minimal cost, and are backed by a manufacturer’s warranty.

    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...
    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...
