CAT Exhaust Manifolds
CAT Exhaust Manifolds
Whether you're replacing a cracked factory manifold or building a high-performance Caterpillar engine, Momentum Worx has the right exhaust manifold for your application. We carry premium exhaust manifolds for CAT C15, C15 ACERT, C13, C13 ACERT, C12, and single turbo conversion applications from the most trusted names in the industry.
Our selection includes Momentum Worx, Steed Speed, and Full Tilt Performance exhaust manifolds, available in both raw cast and high-temperature ceramic coated finishes. Whether you're looking for maximum durability, improved heat management, or a manifold designed for larger aftermarket turbochargers, you'll find the right solution here.
Choose from direct replacement manifolds, T6 conversion manifolds, and performance manifolds engineered to improve reliability while reducing stress caused by repeated heat cycles. Many of our manifolds feature multi-piece construction, allowing for thermal expansion that helps reduce cracking compared to traditional one-piece factory manifolds.
Complete your installation with manifold gaskets, spacers, mounting hardware, turbo studs, and install kits—all available from Momentum Worx to make your project as straightforward as possible.
Whether your truck is built for heavy hauling, daily work, or competition, we offer exhaust manifold solutions designed to keep your Caterpillar engine performing at its best.
