The Diamond Eye Performance DEP220104 turbocharger down pipe is designed for 1989-1993 Dodge 2500 and 3500 trucks equipped with the 5.9L Cummins diesel engine and 2WD drivetrains. This single-exit down pipe is intended for trucks with all cab and bed lengths and features an HX40 turbocharger flange configuration.
