Made in-house by Diamond Eye Manufacturing in Athena, Oregon, this exhaust system is engineered specifically for diesel performance applications. The HX40 downpipe included in this kit is designed for trucks that have upgraded from the factory turbocharger to an aftermarket HX40-style turbo, providing the proper fitment and optimal exhaust flow for enhanced turbo performance.

Important Note: This system is designed for trucks with aftermarket HX40 turbochargers and will NOT fit factory turbo applications. The HX40 downpipe requires an HX40-style turbo discharge flange.
