Product Description
DIAMOND EYE K4312S is a 4.0" T409 stainless cat-back exhaust engineered for the 1994–1997.5 Ford F-250/F-350 7.3L Power Stroke (all cab & bed lengths). This configuration uses a single 4" inlet and dual split rear/split side tailpipes with a high-flow muffler to cut backpressure, lower EGTs, and deliver a deep, refined tone.
FAQ: WILL THIS FIT MY TRUCK?
Yes—if you have a 1994, 1995, 1996, or early 1997 Ford F-250/F-350 with the 7.3L Power Stroke, this cat-back system is designed to fit all cab and bed lengths. (Always confirm your model year is within 1994–1997.5.)
FAQ: WHAT EXIT STYLE DOES THIS KIT USE?
It’s a dual split rear/split side exit. Both tailpipes are included and route cleanly around the axle for OEM-like clearance.
FAQ: WHAT MATERIAL IS IT?
T409 stainless steel tubing and components for corrosion resistance and long service life in harsh climates.
FAQ: DOES IT INCLUDE A MUFFLER?
Yes—this K4312S kit includes a high-flow muffler. If you prefer a no-muffler version, see the K4312S-RP variant (muffler replacement pipe).
