As one of the top ranking small luxury sedans in the country, the Lexus IS does very well in the market. There are few makes that can match the IS utility and comfort and the model carries the Lexus premium-brand badge with flair. Match the IS performance to its looks with a brand new exhaust system. Check out the wide variety available at CARiD to choose from multiple brands. The efficiency of the Lexus IS stock exhaust system is limited. Because of its constrictive design, it does not allow the free flow of exhaust gases and in effect blocks oxygen from flowing into the engine, a flaw that leads to lackluster performance from the engine. Holding onto the stock exhaust system means the car’s performance can only get worse as the stock exhaust ages and wears out. Installing a custom Lexus IS exhaust system from CARiD is the only way to take care of this problem.

Lexus IS Exhaust Systems create low pressure around the engine, allowing the rapid escape of exhaust gases from the engine where the pressure is much higher. This leaves enough space for fresh air to flow into the engine, facilitating a greater increase in engine power output. Another positive thing you will gladly welcome is the throatier note from the custom exhaust system. It’s a note you can fully customize to give your preferred tone and pitch using any of the mufflers available at CARiD. All our Lexus IS exhaust systems are made from sturdy stainless steel. They do not succumb to corrosion, leak or wear out fast. Superior engineering also ensures that they do not break down easily. After the initial buying cost, a custom Lexus IS exhaust will cost you nothing more throughout its lifespan, which is as long as you keep the IS.

      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.
    • Performance Exhaust Systems
      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.

    Not A Cat-Back.
    This is not a Cat-Back system. As it says it is but its not. It's just an axle back. I had to delete my resonator to get the sound i wanted with this exhaust. If you can do that than its definitely something you gotta have. Makes a car sound like a exotic tho. Love the sound.
