Product Description
DIAMOND EYE K4312A is a 4.0" aluminized-steel CAT-BACK dual-exit exhaust system engineered for the 7.3L Power Stroke (1994–early 1997). Mandrel-bent tubing reduces backpressure and helps improve throttle response while the included muffler delivers a deep, mellow tone suitable for towing and daily driving.
FAQ: WILL THIS FIT MY TRUCK?
Yes—if you own a 1994, 1995, 1996, or early 1997 (a.k.a. 1997.5 cutoff) Ford F-250/F-350 with the 7.3L Power Stroke, any cab/bed length. This is a cat-back dual system designed for those model years. Always confirm model year split (early ’97 vs. later ’97.5+) before ordering.
FAQ: WHAT MATERIAL IS IT?
Aluminized steel (not raw aluminum) for strong corrosion resistance at a lower cost than stainless. Diamond Eye typically supplies a stainless muffler even in aluminized series kits.
FAQ: WHAT’S INCLUDED?
Cat-back dual tailpipes, muffler, clamps, and hardware to install with common hand tools using factory-style hangers. Tips are usually optional add-ons.
