Product Description
DIAMOND EYE K4340S-RP is a 4.0" T409 stainless cat-back, dual-exit exhaust for 2003.5–2007 Ford F-250/F-350 6.0L Power Stroke. This RP (muffler replacement) version deletes the muffler for maximum flow and an aggressive tone, while retaining a stock-style split rear/side exit. Mandrel-bent tubing and robust hangers deliver long-term durability and easier install.
FAQ: WHAT DOES “RP” MEAN?
“RP” = muffler replacement. This kit uses a straight pipe in place of the muffler. If you want the same system with a muffler, see cross-references below.
FAQ: WILL IT FIT MY TRUCK?
Fits 2003.5–2007 Ford F-250/F-350 6.0L Power Stroke, all cab and bed lengths, 4x4 applications. Designed as a direct bolt-on cat-back dual system with split rear/side exits.
FAQ: MATERIAL & SOUND
Constructed from T409 stainless steel for corrosion resistance. With the RP (no muffler) configuration, expect a deeper, louder exhaust note versus the muffled kit.
