Description

The Diamond Eye Performance K4327A-RP is a 4-inch aluminized steel turbo-back exhaust system designed for 1999-2003 (early 2003) Ford F-250, F-350, F-450, and F-550 Cab & Chassis trucks with the 7.3L Powerstroke diesel engine and automatic transmission. This performance exhaust system replaces the factory exhaust from the turbo outlet to the tailpipe, featuring a muffler-delete design for an aggressive sound. It offers increased fuel economy, lower exhaust gas temperatures (EGTs), improved horsepower and torque, and better throttle response. The system is made in the USA with mandrel-bent tubing for maximum flow and utilizes OEM hangers for an easy bolt-on installation. It comes with a 1-year limited warranty on the aluminized kit.
