EXHAUST MANIFOLDS

Exhaust manifolds are a crucial component in any vehicle's exhaust system, responsible for collecting exhaust gases from the engine's cylinders and directing them out through the exhaust pipe. A high-quality exhaust manifold can improve engine performance, increase fuel efficiency, and reduce emissions.

The exhaust manifolds in this category are specifically designed for GM Duramax diesel trucks, with options available for various models and years. Brands like PPE, AFE Power, Wehrli, BD Diesel, and ATS offer a range of exhaust manifolds with different features and benefits to suit your specific needs.

Whether you're looking for high-performance manifolds, compound turbo race manifolds with up-pipes, ported ductile iron manifolds, or twisted steel up-pipes, this category has you covered. Many of the products come with gaskets, hardware, and other necessary components for easy installation.

If you're in the market for a new exhaust manifold to improve your vehicle's performance and efficiency, browsing through this category will provide you with a variety of options to choose from. Upgrade your exhaust system with a top-quality exhaust manifold that meets your needs and specifications.
