Product Description
DIAMOND EYE K4327A is a 4.0" aluminized steel turbo-back exhaust engineered for the 2000–2003.5 Ford F-250/F-350 Super Duty 7.3L Powerstroke Cab & Chassis (automatic transmission, non-catalyst). It replaces restrictive factory tubing from the turbo outlet back, delivering lower EGTs, crisper throttle response, and a deeper tone. Includes a straight-through muffler for strong flow with controlled cabin resonance.
FAQ: WILL THIS FIT MY TRUCK?
Yes—if you have a 2000–early 2003.5 7.3L Powerstroke Cab & Chassis (not pickup bed) with automatic transmission and non-catalyst configuration. Verify wheelbase and C&C configuration before purchase.
FAQ: IS IT CALIFORNIA LEGAL?
The included diesel downpipe is listed under CARB Executive Order D-778-1. However, complete turbo-back systems for these years are intended for non-catalyst configurations; always check your local and state regulations before installation.
FAQ: WHAT EXIT AND SOUND SHOULD I EXPECT?
This kit is a single passenger-side exit. The included muffler yields a deep, authoritative tone without excessive drone in typical C&C applications.
