Squeeze maximum power and torque out of your GMC Topkick engine with any of the high performance exhaust systems available at CARiD. There is an exhaust system for every GMC Topkick truck, from 1990 models to 2009 editions. When choosing between exhaust systems, go for the exhaust that is custom built for your Topkick engine. Performance exhaust manufacturers are very particular about results and match each exhaust system to a specific engine size and car specifications in order to acquire the best results. Attempting to install a GMC Topkick custom exhaust system that is deigned for a bigger engine may lead to loss of power instead of achieving the intended purpose of increasing horsepower. With exhaust systems and exhaust kit from top manufacturers such as Borla, MagnaFlow, Flowmaster, Gibson, RBP, MBRP, Onki, Weapon-R and dB, you will have an easy time choosing what works for your truck.

Direct replacement exhaust systems from any of these brands give between 5% and 10% additional horsepower and torque. With the additional power, your truck’s towing power is enhanced and hauling the truck in tricky road conditions is no longer a big challenge. The engine will release more power at low rpm, meaning your drives will be more thrilling and fulfilling. Throttle response is enhanced and you will enjoy a shorter waiting period between the time you press the accelerator and the time power hits home. Overall efficiency in the engine is boosted and unburned fuel mixture no longer leaves the engine. The result is better fuel consumption and increased fuel mileage for you. Your GMC Topkick will sound a lot better than it ever did with a custom exhaust system fixed into place - the new exhaust note is deeper and more pronounced than the stock/OEM exhaust sound.

      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.

    GMC Topkick Performance Exhaust Systems Reviews

    Average rating:  5  5 - 1 review

    AP Exhaust
    My GMC was performing badly going up the hills and mechanic coded it and all the mistakes were related to O2 sensors, I needed a really good converter which could fix all these issues and with long time service warranty, a friend of mine recommended me CARiD and so will do I - also recommend it. Mechanic put it on, and it was the best day of my GMC life.
