Product Description
DIAMOND EYE K4312S-RP is a 4.0" T409 stainless cat-back exhaust system engineered for 1994–1997.5 Ford F-250/F-350 7.3L Powerstroke (all cabs & bed lengths). This kit uses a single 4" inlet and dual 4" tailpipes with split rear/split side exits and comes with a muffler replacement pipe (no muffler) for maximum flow and an aggressive tone. CNC mandrel-bent tubing, OE-style hangers, and included hardware deliver a durable, bolt-on upgrade.
FAQ: WILL THIS FIT MY TRUCK?
Yes—if you have a 1994, 1995, 1996, or early 1997 (1997.5 cutoff) Ford F-250/F-350 with the 7.3L Powerstroke, this cat-back fits all cab and bed lengths. Always verify the model year break (1997 vs. 1997.5) before ordering.
FAQ: DOES IT INCLUDE A MUFFLER?
No. The -RP suffix means muffler replacement pipe is included and the muffler is deleted for straight-through flow.
FAQ: WHAT MATERIAL IS USED?
409 stainless steel (T409) for corrosion resistance and long service life in harsh climates.
