Up the aggression with a more intimidating exhaust note and more power production with one of our advanced exhaust systems from American Trucks. Swapping the exhaust system on your pickup truck is a quick way to boost your power production and to make your truck sound a whole lot more powerful as well. That's why we offer so many different truck exhaust parts for purchase. The exhaust system on your Sierra determines how it sounds as you drive around, and we offer specially designed kits that will give it a larger, more aggressive rumbling sound as you drive down the road. Not only can an upgraded exhaust kit make your truck sound more intimidating, but it can also actually boost power production. That's because the exhaust system is in charge of removing exhaust fumes from your engine. The more efficiently it handles this task, the more power your engine can produce as well. That means getting a wider or more efficient exhaust system often results in modest horsepower and torque increases. If you invest in one of our advanced Sierra cat-back exhaust systems you'll be impressed by what it can offer to your system. This is especially true if you also invest in an improved cold air intake, and perhaps a wider throttle body for your pickup. All these minor changes can lend real power to your Sierra's engine and make it produce significantly more power as you drive around. We also sell more specialized kits like our Sierra side exit exhausts. These offer smoother and more efficient pathways that will help you produce even more power. Our exhaust parts are made from stainless steel or aluminum for maximum corrosion resistance. They're designed with wide and smooth pathways and often feature mandrel-bend turns for fewer kinks and faster exhaust flow overall. It's all these slight improvements over the stock systems that will help your Sierra generate more power and run more smoothly with an upgraded system.
