The Diamond Eye K5323A is a 5-inch turbo-back exhaust for a 2000 to early-2003 7.3 Powerstroke pickup. It is the aluminized kit with the muffler. The downpipe is 4 inches and steps to 5. The no-muffler kit is K5323A-RP. A van will not take this system.

It replaces the pipe from the turbo back in mandrel-bent aluminized steel and uses the factory hangers. The muffler is Diamond Eye’s straight-through piece, a deeper tone without a straight-pipe bark. It is for an automatic, non-catalyst truck. CARB EO D-778-1 is on the kit. Aluminized steel will rust sooner than stainless in salt.

It fits 2000, 2001, 2002, and early-2003 F-250 and F-350 pickups, all cab and bed lengths, with an automatic and no catalyst. It does not fit an E-Series.
