The Pontiac G8 is a powerful, domineering machine. Driving this car gives you an extraordinary feeling of self-confidence. You feel like you are in total control, as if you hold the final say on the highway. Still, the Pontiac G8 engine performance can do with a little boost. Stock exhaust systems restrict the flow of exhaust gases from the cylinders thereby limiting the amount of power produced, and the same is true of the Pontiac G8. To experience the ultimate fun-ride, you need to replace the stock exhaust system with a performance exhaust system from CARiD. Performance Pontiac G8 exhaust systems are widely available under different brands from CARiD. They enhance vehicle performance by increasing the speed of exhaust flow and enabling rapid inflow of fresh air into the cylinders. As a result, your engine produces more horsepower and torque, enabling faster acceleration and better performance.

Aftermarket Pontiac G8 exhaust systems also improve fuel consumption. This is especially true when cruising on a highway. You realize that more miles are covered on the same tank of fuel. Besides great performance, you get great sound. Performance exhaust systems provide a deep manly tone to match the power in your car. You may also have the sound customized to the tone and pitch of your choice. Thanks to the high-tech audio engineering technology used in putting the exhaust system together, the sound quality remains just as strong and powerful over the years. All exhaust system brands at CARiD come with a lifetime warranty from the manufacturer, which is a statement of the quality of materials and expertise used in constructing the exhaust and remains active for as long as you own the G8. An installation manual is also available to guide you or the auto technicians who will be doing the installation through the process.

      Here's A 'Tip': Exhaust Tips Are An Easy Way To Dress Up Your Tailpipe
      Performance exhaust systems give you improvements in power output, sound levels, and appearance, all in one package. But let's face it: not everyone has the spare change to buy and bolt up one of these kits. So you soldier on with what you have. And that may be a tired-looking exhaust system that is still functional. You've spent all day washing and waxing the vehicle's paint and chrome to perfection, but no degree of elbow grease will make that tailpipe look better.

      Are Headers Worth The Performance Improvement?
      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.

      Are X-pipes and H-pipes Better Than Straight Pipes on Dual Exhaust Systems?
      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.

      Power, Sound, Looks | Can I Have It All With a Cat-Back Exhaust System?
      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?

      Pickup Truck Cab And Bed Sizes Are Important When Selecting Accessories
      Americans love to have choices. Buying a dress shirt? Decide solid or stripe, short or long sleeve, cotton or poly blend, button or spread collar, regular fit, slim fit, or big & tall. How about a meal at your favorite steak house? Will it be porterhouse, T-bone, or sirloin? Cooked rare, medium-rare, or medium? With baked, mashed, or French fried potatoes? Thirsty for a fancy cup of coffee? Let's not even get started on options that let you end up with a "grande caramel macchiato with 1% low-fat milk, 2 Splendas, and an extra espresso shot".

      Direct Fit vs. Universal Mufflers
      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.
