Luxury cars such as the Buick PARK Avenue are an irresistible indulgence for many. But luxury plus superior performance are addictive. You can get both from your Buick Park Avenue if you replace the stock exhaust with a custom exhaust. If you have already replaced the exhaust system with an OEM exhaust or one of the cheap exhausts in the market, consider getting a performance exhaust from CARiD instead. These exhausts are specially built to bolster the performance of the Park Avenue engine, giving an additional 7-10% in horsepower. To enjoy the highest boost in power and torque, buy one of the exhausts built by Flowmaster. The brand has manufactured a range of exhaust systems for all Park Avenue models, and they are all readily available at the CARiD shop. Cat back exhaust systems from Borla, MagnaFlow and Onki are also available and will give similar results.

If you do not want to replace the entire exhaust system just yet, installing a custom header, muffler, pipes or catalytic converter will substantially improve engine power. These are also available at the shop, and come in renowned brand names such as Onki, RBP, Borla, Zunden and MBRP. Another benefit you will get from a custom exhaust is improved fuel efficiency. The Park Avenue engine will be able to burn fuel much more efficiently so that none goes to waste. Consequently, you will manage to drive more miles at full tank. Fuel savings are only one half of the savings you will make, the other half being cost. Given their quality and the kind of exceptional service they give, Park Avenue custom exhausts are affordably priced and do not require constant replacement. You only buy them once and get years of good service in return.

    • Performance Parts
      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 systems less restrictive. These parts increase the flow of air into the engine and ease the flow of exhaust gas out of the engine. Among these components, headers may be the most difficult to install. In this article, we’ll discuss what headers do, their different types, and how much performance they can add to your car.
    • Performance Parts
      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.
    • Performance Parts
      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 sound of a car with its exhaust. After all, doesn’t everyone have a childhood memory or two of a car and the particular sound it made?
    • Performance Parts
      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 between these two styles so you can make a more informed purchase.
