Product Description
DIAMOND EYE 122003 TURBO DOWNPIPE – 94–97.5 FORD F-250/F-350 7.3L (SECOND SECTION, NO OXYGEN SENSOR BUNG) – 3" INLET/OUTLET, ALUMINIZED
This Diamond Eye second-section turbo downpipe replaces the downstream half of the factory 7.3L Power Stroke downpipe on 1994–1997.5 F-250/F-350 trucks.
