Product Description
DIAMOND EYE K5323S is a 5" 409 stainless steel turbo-back exhaust system for the 7.3L Powerstroke. It replaces the factory system from the turbo outlet back with a 4" downpipe, free-flow muffler, and passenger-side single tail exit for lower EGTs, quicker spool, and a deep, authoritative tone. Designed for automatic-transmission, non-catalyst models. Made in the USA.
FAQ: WILL THIS FIT MY TRUCK?
Yes—if you have a 2000–2003.5 Ford F-250/F-350 Super Duty 7.3L Powerstroke with an automatic transmission and non-catalyst configuration. Works with all cab and bed lengths. Early 2003 (2003.5 and earlier) 7.3L only—does not fit 6.0L models.
FAQ: WHAT’S INCLUDED?
4" turbo downpipe, intermediate/over-axle pipes, 5" tail section, straight-through muffler, and hardware/hangers for a bolt-in install (reuses OE-style mounting points).
FAQ: WHAT MATERIAL IS IT?
409 stainless steel tubing and components for durability in high-heat diesel service.
FAQ: SOUND LEVEL?
Deep, moderate tone with the included muffler—noticeable under throttle, comfortable on the highway.
