Product Description
DIAMOND EYE K4325A is a 4.0" aluminized turbo-back exhaust system for the 2000–2003 Ford E-Series 7.3L Power Stroke (automatic, non-catalyst). It replaces the restrictive factory system from the turbo to the tail, improving flow, reducing backpressure, and delivering a deeper tone while maintaining drivability. Includes a straight-through muffler and passenger-side single exit.
