We proudly carry products from Grand Rock, because we know they've been providing high-quality exhaust system components for nearly 50 years. The manufacturer uses over a dozen different machines and the latest software to ensure that their customers get high-quality exhaust solutions.Grand Rock makes over 95% of its products in-house. So when it's time to upgrade, maintain, or replace your exhaust system, you can do it confident that you're getting American quality and supporting American workers.Grand Rock Exhaust ProductsWhether you own one rig or manage a fleet, you know that exhaust problems can result in significant downtime and lost hauling opportunities. High-quality Grand Rock components keep your rig performing optimally and within DOT regulations.MufflersA well-built muffler keeps your rig compliant with federal pollution standards and federal, state, and local noise emission regulations. It improves engine performance by minimizing backpressure and reducing the risk of overheating due to improper airflow. A quality muffler can even save you on fuel and preserve horsepower.We offer Grand Rock mufflers in various sizes and configurations to match your rig. You can also choose a custom muffler and outlet patch.Exhaust TubesHigh-grade pipes provide airflow, emissions compliance, and optimal engine performance, and prevent dangerous gases from entering the cab. Select Grand Rock Y-pipes, S-pipes, curved top, or other tubes for Kenworth, International, Freightliner, and other semi manufacturers, or find a specific part to fit your custom industrial or fabrication needs.ClampsYour exhaust tubes need quality-made clamps to keep them firmly in place. Unsecured tubes, especially large-diameter ones, can lead to costly damage. We offer Grand Rock clamps for horizontal and vertical applications in sizes ranging from 2.5 to 8" and in a variety of finished materials.ElbowsHorizontal and vertical exhaust systems demand high-quality elbows. If you're experiencing a loss in fuel economy or engine power, or hear hissing or rumbling noises, a damaged elbow may be the culprit. In custom tube applications, elbows give you the flexibility to go around beams, walls, or other obstacles. We offer hundreds of high-quality Grand Rock elbows in various sizes, so it's easy to find the proper fit.EGR Flex BellowsYour exhaust gas recirculation, or EGR, flex bellows take on vibration, parts movement, and thermal expansion. You can't replace them with just any flex hoses, or you risk leaks in high-temperature areas that face significant stress.Opt for Grand Rock flex bellows in various sizes, constructed from multiple layers of stainless steel to prevent leaks and withstand harsh conditions. They get the job done right, transporting your exhaust from the manifold to the EGR valve or through your cooler for recirculation.Shop Truck Pipes USA for Quality and Top-Rate ServiceThe Grand Rock exhaust parts and other products we sell adhere to IATF 16949:2016 quality standards, so you can shop with confidence.
