Diamond Eye KIT 4in Catback MFLR RPLCMENT PIPE SGL AL: 03-07 FORD 6.0L F250/F350 (Extended Cab Only)

If you're looking to replace the muffler section of your 2003-2007 Ford F-250 or F-350 with the 6.0L Powerstroke engine, this cat-back replacement pipe from Diamond Eye is a solid option. This kit is specifically designed to fit between the catalytic converter and the rear axle, effectively bypassing the muffler for a more direct exhaust flow.

Diamond Eye uses CNC mandrel bending to shape this 4-inch aluminized steel pipe, which helps maintain consistent diameter for improved exhaust gas flow compared to crushed bends. Aluminized steel offers a good balance of durability and cost for exhaust components. This pipe is intended as a direct replacement for the factory muffler section, making installation more straightforward if you're aiming for a louder exhaust note and potentially a slight improvement in throttle response.

This kit is designed for the extended cab models of the F-250 and F-350. Ensure you have the correct cab configuration before installation. It's a straightforward way to alter your truck's exhaust sound and performance.
