Product Description
DIAMOND EYE K4331A-RP is a 4.0" aluminized steel, turbo-back, single–passenger-side exhaust system engineered specifically for the Ford F-550 Rollover (cab & chassis/flatbed) with the 7.3L Power Stroke. Deleting the muffler reduces backpressure and helps the turbo spool quicker, while the large-radius mandrel bends maintain flow for lower EGTs and a purposeful tone. Designed for the unique F-550 frame/axle routing used on rollover/flatbed configurations.
FAQ: WILL THIS FIT MY TRUCK?
Intended for 2000–2003.5 F-550 7.3L Power Stroke Rollover (cab & chassis), automatic transmission, non-catalyst trucks. It will not fit F-250/350/450 pickups and may not fit extended bed configurations without additional parts. Always verify your truck is an F-550 cab & chassis and check the build date (early 2003 cutoff). Sources: Diamond Eye application notes and dealer fitment listings.
FAQ: DOES THIS INCLUDE A MUFFLER?
No. The -RP suffix denotes no muffler (straight-through turbo back). If you want the same kit with a muffler, see cross-reference K4331A.
FAQ: WHAT MATERIAL IS IT?
Aluminized steel tubing and components for durability and value in work-truck environments. All clamps/hardware required for installation are included per typical kit contents.
