Product Description
DIAMOND EYE K4325A-RP is a 4.0" aluminized turbo-back exhaust system for Ford E-Series vans, engineered for lower backpressure, quicker turbo spool, and a deep, authoritative tone. This configuration is the single-pass, no-muffler version in Diamond Eye’s Performance Series, built from mandrel-bent tubing for maximum flow.
Official Diamond Eye fitment centers on 2000–2003 Ford E-Series 7.3L Power Stroke (automatic, non-catalyst). Many retailers list coverage that extends to 1998–1999 model years; always verify your emissions equipment and transmission before purchase.
FAQ: WILL THIS FIT MY VAN?
Manufacturer listing covers 2000–2003 E-Series 7.3L (automatic, non-catalyst). If your 1998–1999 E-Series has similar exhaust layout (no catalyst) it may fit, but confirm before ordering.
FAQ: DOES THIS INCLUDE A MUFFLER?
No. This is the muffler-delete (straight-through) kit. If you prefer a muffled version, see the related kit below.
FAQ: MATERIAL & SOUND
Aluminized steel for durability and value. Expect a deeper, more aggressive tone versus stock, and reduced EGTs under load compared with factory piping.
