Harness the power within your Hummer H3T engine with a new custom exhaust system from CARiD. Hummer H3T custom exhaust systems are designed and put together using a very different concept from that used to make the stock exhaust system. Everything about their size and design is all about enhancing engine scavenging in order to increase the engine’s capacity to intake of clean air and fuel for engine generation. There is a range of Flowmaster cat back exhaust systems for the Hummer H3T to choose from, as well as performance headers, mufflers and exhaust kits from Zunden, MagnaFlow, Gibson and MBRP. Installing a complete exhaust system will boost engine power by as much as 10-12%. Combining the exhaust system with a performance header will top it up by another 10-20hp. All this extra power will enhance your H3T’s towing power, increasing the force with which it pulls up and tows along in tough road conditions.

Because the custom exhaust enhances the H3T engine’s overall efficiency, one of the areas you will begin to notice improvements is in fuel consumption. With fuel now burning more efficiently, your fuel mileage will increase by 1-2mpg on average. As you begin to drive longer miles on the same amount of gas, this ease will be reflected on your pocket. Fuel is not the only thing you will save on. You also save on car maintenance costs when you buy a performance exhaust system from CARiD. Unlike the cheap exhaust options flooding the market, our custom exhausts give you real value for money. All Hummer H3T aftermarket exhaust systems on sale come with a lifetime warranty or limited lifetime warranty, and will remain effective for as long as you keep your Hummer. They won’t need to be replaced due to failing performance or wear.

      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.
