The Mercury Grand Marquis is a powerful 4 door sedan ideal vehicle for commuting or travelling long distances. Powered by a big 4.6L V8 engine with an automatic transmission system, it is the ultimate model of reliability. But if you are looking for top performance from your car, you need to replace your stock exhaust system with a performance exhaust system from CARiD. Stock exhaust systems restrict exhaust flow because all the cylinders have to share a single manifold. On the other hand, aftermarket exhaust systems optimize engine operations resulting in increased power, fuel cost savings and great sound. Aftermarket Mercury Grand Marquis exhaust systems reduce pressure and turbulence, increasing the flow of exhaust gases from the cylinders and flow of fresh air into the engine. The benefits accruing to you include greater horsepower and significant torque gains. The car is now able to accelerate faster than before.

Driving also becomes a more pleasurable experience and your vehicle now consumes less fuel than it did in the past. Also, you have the advantage of great sound accompanying the increased engine power. The deep throaty sound is a sure sign that you are now leading from the front. Sound quality is guaranteed through a sophisticated engineering process that ensures sound degradation does not occur. Aftermarket performance exhaust systems do not succumb to rusting. They are made from austenitic stainless steel, a material that is extra resistant to corrosion. The manufactures also provide a lifetime warranty to go with the product. The warranty is an indication of the material quality and workmanship employed in the manufacture of the product. The polished tip in each aftermarket Mercury Grand Marquis exhaust system complements the gleam of your car for an ultra-urbane look.

    • 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.

    Supper Cool Sound!
    I bought this for my Mitsubishi and it sounds awesome! It's got a 3.5 l v6 and it makes it sound like its very souped up! And almost like it has a v8 in it. I couldn't be more happy with this product the sound will blow your mind on whatever you choose to put it on whether it be a six cylinder like I put it on or a v8 very much recommend this product if you want a really nearly sound.
