f you’re running a Paccar MX13 Gen 1 (2010–2013) and want to help that engine breathe easier, the PDI Performance Exhaust Manifold is a serious upgrade over the factory setup.
Built right here in the USA, the PDI MX13 Exhaust Manifold is engineered to improve exhaust flow where it matters most. With redesigned internal passages, this manifold delivers an average 20% increase in airflow in key areas, helping exhaust gases move more efficiently out of the engine and into the turbo.
Better airflow means the turbo can do its job easier, which can translate to stronger performance, improved efficiency, and up to 100° cooler EGTs under load. Lower exhaust gas temperatures help reduce stress on engine components, making this manifold a great choice for trucks that spend their lives working hard.
Whether you’re replacing a cracked factory manifold or upgrading for better performance and reliability, the PDI MX13 Exhaust Manifold is built to handle the heat and keep your truck pulling strong.
