CUMMINS ISX Exhaust Manifolds

CUMMINS ISX Exhaust Manifolds

Cummins ISX Exhaust Manifolds

Whether you're replacing a cracked factory manifold or upgrading your engine for more horsepower, Momentum Worx has one of the largest selections of Cummins ISX exhaust manifolds available. We carry premium manifolds for CM570, CM870, CM871, CM2250, CM2350, CM2450, and X15 applications from trusted manufacturers including Momentum Worx, Full Tilt Performance, and Steed Speed.

Choose from stock VGT replacement manifolds, T6 conversion manifolds, 1-piece, and 3-piece designs to match your build. Whether you're keeping your factory VGT turbocharger or converting to a larger T6 turbo, we have the right manifold for the job.

Our selection includes heavy-duty cast manifolds designed to withstand years of abuse, along with premium multi-piece designs that reduce stress from repeated heat cycles. Three-piece manifolds allow each section to expand independently, helping minimize cracking, improve gasket life, and increase long-term reliability compared to traditional one-piece manifolds.

Looking for improved heat management? We also offer high-temperature ceramic coated manifolds that help retain exhaust heat inside the manifold, reduce underhood temperatures, improve corrosion resistance, and give your engine bay a premium appearance.

Complete your installation with manifold gaskets, spacers, mounting hardware, turbo studs, turbo gaskets, and complete install kits from Momentum Worx. Whether you're replacing a leaking manifold or building a 1,000+ horsepower ISX, you'll find everything you need to complete the job right the first time.
