The Kia Optima is among the most popular mid-size sedans. Ample space, comfort, tasteful interiors, stylish outline and a potent engine are among Optima’s top attractions. But even with all these positives, it suffers the laxity brought about by a weak stock exhaust system. Like any other stock exhaust, the Optima stock exhaust is limited when it comes to exhaust gas control. Narrow pipes and a constrictive design make it difficult for spent gases to make their way out of the engine and through the exhaust system. A custom exhaust system changes all that. Designed to give optimal exhaust flow, custom Kia Optima Exhaust Systems increase the engine’s capacity to produce power by maximizing the flow of clean air into the engine. Get superior quality Kia Optima exhausts from CARiD where options such as the Borla cat back exhaust system for the Kia Optima are among the bestselling units on offer.

Using a performance header alongside the exhaust system will give you the highest increase in horsepower and is worth going for when you want to push the Optima engine to its highest potential. In addition to the gains in power, an aftermarket Kia Optima exhaust system enhances engine efficiency to give better fuel consumption. By increasing exhaust scavenging, the new exhaust pipes ensure that there are no impurities within the engine. Fuel burns purer to give more power, and the low backpressure created by the exhaust system prevents unburned fuel from flowing into the pipes and going to waste. You will be grateful for the extra 1-2mpg you get as a result of all this. Not forgetting the classic booming roar of a custom Kia Optima exhaust system which makes the car sound more powerful than it looks.

      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.
