Diamond Eye Manufacturing K4209A-HX40 4" Turbo Downpipe Kit with V-Band for 89-93 Dodge Cummins 5.9L

The Diamond Eye Manufacturing K4209A-HX40 is a complete 4-inch turbo downpipe kit engineered specifically for 1989-1993 Dodge Ram trucks with the 5.9L Cummins diesel engine in 2-wheel drive configuration. This performance exhaust kit is designed for vehicles equipped with or upgrading to an HX40 turbocharger.

Key Features:

• 4-inch aluminized steel construction for durability and corrosion resistance
• V-band connection for secure, leak-free turbo attachment
• Single exit configuration optimized for 2WD chassis clearance
• Direct-fit design for HX40 turbo applications
• Reduces exhaust backpressure for improved turbo efficiency and performance
• Complete kit includes downpipe and necessary hardware

This downpipe kit is an essential component for maximizing the performance potential of your HX40-equipped Cummins diesel. The larger 4-inch diameter significantly reduces exhaust restriction compared to the factory downpipe, allowing the turbocharger to spool more efficiently and improving throttle response. The V-band connection ensures a secure, leak-free seal at the turbo outlet while simplifying installation and future maintenance. Note that this kit is designed exclusively for 2-wheel drive applications due to chassis and driveline clearance differences.
