Product Description
DIAMOND EYE K4327A-RP is a 4.0" aluminized steel turbo-back, single-exit exhaust system engineered specifically for 2000–2003.5 Ford F-250/F-350 Cab & Chassis trucks with the 7.3L Power Stroke. It deletes the muffler for maximum flow, quicker turbo response, and lower EGTs while using mandrel-bent tubing and OE-style hangers for a clean, bolt-on install.
FAQ: WILL THIS FIT MY TRUCK?
Yes—if you have a Cab & Chassis (not a pickup) Ford F-250/F-350 with the 7.3L Power Stroke and automatic transmission from model years 2000 through early 2003 (2003.5 cutoff). This kit is for non-catalyst trucks and follows the Cab & Chassis frame routing. Always confirm your configuration before ordering.
FAQ: WHAT SOUND SHOULD I EXPECT?
With the straight-pipe design, expect a deep, aggressive tone under throttle and a mellow cruise note. Sound level varies with turbo, tuning, and tip choice.
FAQ: IS THIS LEGAL IN MY STATE?
The included diesel downpipe style used in this application is covered by CARB EO D-778-1 for qualifying diesel applications. Full turbo-back, no-muffler systems may be intended for off-road/competition use where applicable—verify your local and state regulations before purchase and installation.
