Dump your Infiniti G37 stock exhaust system for a brand new custom exhaust system and realize a whole new world of power. Aftermarket exhaust systems are nothing like the stock exhaust and are built to facilitate the unrestricted flow of exhaust gases. Their design and width of exhaust pipes makes this possible and increases the engine’s capacity to generate power. Get the finest quality Infiniti G37 Exhaust Systems from CARiD, the leading auto parts dealer in the country. In stock are complete exhaust systems for the Infiniti G37 from Borla and MagnaFlow as well as headers, mufflers, catalytic converters and exhaust tips from the same brands and others like Flowmaster, Gibson, MBRP, Onki, Weapon-R and RBP. Replacing the entire stock exhaust system is the best option when you want to squeeze maximum power from the engine.

More power means more pulling force, most noticeable as greater towing power. It’s amazing how faster and easily your Infiniti G37 will be able to pull along when you’ve fixed the new exhaust into place. The new exhaust note will announce your presence long before you show up but is not too loud as to irritate. Neither does the sound level violate any state laws on noise. In fact, you can moderate the sound range of your Infiniti G37 exhaust system by playing around with the mufflers from the impressive range available at the CARiD store. Customizing the sound allows you to enjoy the exact tone and pitch you would love to get from your car. The aftermarket exhaust system works seamlessly and fits right into the engine cylinders because it is made to fit. We have exhaust systems for each Infiniti G37 model so it will be easy to find one that is custom built for your car.

      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.
