Product Description
DIAMOND EYE K4308A is a 4.0" aluminized-steel turbo-back exhaust engineered for the 1994–early-1997 Ford F-250/F-350 7.3L Power Stroke. This system uses a 3" two-piece downpipe, a straight-through muffler, and dual split exits (rear + side) for lower EGTs, quicker turbo spool, and a deep, controlled tone.
