The Buick Rainier is one of the most successful mid-size SUV models ever sold. Yet it can be upgraded to give even more power than is released by the stock components. Installing a custom exhaust system is one of the easiest ways to boost performance. Stock exhausts, including the Rainier exhaust system, are made in a smaller size than they should be. This is done in an effort to keep the cost of production down. One reason why a custom exhaust system is best for your car is because it has wide exhaust pipes and headers that are a precise fit for the engine. This automatically increases exhaust flow, leaving the engine to perform optimally. As a result, your engine gives more horsepower and torque. Find the best quality custom exhaust systems at CARiD. The shop stocks different exhaust models for the Rainier from top manufacturers such as Flowmaster, MagnaFlow, Borla, Gibson, MBRP, Zunden, Weapon-R and Onki.

With the Flowmaster cat back system for the Rainier, you can expect between 5% and 10% more power. Individual exhaust parts that you can custom fit into the existing exhaust system for a change in tone and performance are catalytic converters, headers and exhaust mid-pipes from Borla, RBP, Flowmaster, Gibson, MagnaFlow, MBRP, Onki and Weapon-R. In addition to increase in power and torque, a custom exhaust will give your Rainier a deeper exhaust note. There are variations in the sound produced by each exhaust system, and you have plenty of options to choose from. From a deep, roaring sound to a mild, controlled rumble or a loud but clean note, you will achieve the sound you want with a custom exhaust from CARiD.

      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.
