Full Tilt Performance Ceramic Coated Exhaust Manifold for 2011-2021 Cummins ISX CM2250, CM2350 & X15

Full Tilt Performance Exhaust Manifolds are engineered to produce noticeably superior results over your OEM exhaust manifold. Full Tilt uses better materials and a better design to improve exhaust flow, reduce temperatures and increase longevity and reliability over a stock manifold. Heavy duty thick flanges and center dividers offer increased strength and durability. Sharp turns and twists are eliminated to create smooth airflow to the turbo. All joints are designed with tighter tolerances, fifty percent more surface contact, and are press-fit to ensure that they never leak. Pressure fitting before surfacing means your Full Tilt Exhaust Manifold comes out of the box in one piece. It does not come in three pieces like an OEM manifold. They are also test mounted on a head to verify proper alignment before the ever leave Full Tilt.

The result of better engineering, better production, better materials and a better design is an exhaust manifold that delivers everything a big rig owner wants. Full Tilt exhaust manifolds have smooth interior surfaces that are hand-finished. Then a high-temperature-resistant proprietary CeramiChrome ceramic coating is applied. This coating keeps exhaust gas energy inside the manifold, improving turbo response. Lastly, all Full Tilt manifolds are flow-tested to make sure they flow a minimum of twenty CFM per port.
