Diamond Eye 122001 3" Aluminized Downpipe First Section 1994-1997.5 Ford 7.3L Powerstroke

The Diamond Eye 122001 is a 3-inch aluminized steel replacement downpipe — first section — engineered for 1994–1997.5 Ford F-250 and F-350 trucks equipped with the 7.3L Powerstroke diesel engine. Compatible with all cab and bed length configurations, this direct-fit section is designed to replace the restrictive factory turbine outlet pipe and restore or upgrade exhaust flow from the turbocharger.

Key Features:

• 3" mandrel-bent aluminized steel construction for improved flow and durability over the OEM crushed factory downpipe
• First-section replacement — designed specifically as the upper section of a two-piece downpipe assembly connecting directly to the turbocharger outlet
• Reduces exhaust backpressure to support lower exhaust gas temperatures (EGTs) and improved power under load or while towing
• Improves turbo spool and throttle response for stronger low-end torque on stock or modified 7.3L Powerstroke builds
• Direct-fit design compatible with OEM-style turbo outlet and factory exhaust routing on OBS 7.3L Power Stroke trucks
• C.A.R.B. Exempt — Executive Order #D-778
• Compatible with all cab and bed lengths for 1994–1997.5 F-250 and F-350

Diamond Eye Performance manufactures this downpipe section using mandrel-bending technology to eliminate the sharp, flow-robbing bends found in the stock unit. Upgrading the first section of the downpipe is a smart foundation mod that pairs well with performance intakes, larger exhaust systems, and custom tuning for the 7.3L Powerstroke platform.
