7.3 OBS Powerstroke 4" Aluminized Turbo-Back Exhaust with Muffler – Diamond Eye K4306A

Upgrade your 1994–early 1997 Ford F-250 or F-350 7.3L Powerstroke with the Diamond Eye K4306A 4-inch aluminized turbo-back exhaust system. This complete kit replaces the restrictive factory exhaust from the turbo back, delivering stronger flow, lower EGTs, improved throttle response, and a deep, aggressive diesel tone while retaining the factory catalytic converter.

• Includes 3" two-piece downpipe for easier installation in the tight OBS engine bay
• High-performance muffler for a refined yet aggressive sound
• Single passenger-side exit
• Direct bolt-on design that reuses OEM hangers
• Fits all cab and bed length configurations
• Tip not included
• CARB EO D-778

Benefits

• Reduced backpressure and lower exhaust gas temperatures
