The Diamond Eye K4325A is a 4-inch turbo-back exhaust for a 2000–2003 E-Series 7.3 Powerstroke. It is the aluminized kit with the muffler. A pickup or a cab-and-chassis will not take this system.

It replaces the pipe from the turbo back in 4-inch mandrel-bent aluminized steel and uses the factory hangers. The exit is passenger side. The muffler is a straight-through piece, a deeper tone without a straight-pipe bark. It is for an automatic, non-catalyst van. The muffler-delete kit is K4325A-RP. CARB EO D-778-1 covers the downpipe. Aluminized steel will rust sooner than stainless in salt.

It fits 2000–2003 E-250, E-350, and E-450 vans with an automatic and no catalyst. It does not fit an F-Series. The cab-and-chassis kit is K4327A.
