DIAMOND EYE K4332A-RP TURBO BACK EXHAUST 00-03 EXCURSION 4 INCH SINGLE PASS NO MUFFLER ALUMINIZED DIESEL EXHAUST

DIAMOND EYE K4332A-RP is a 4.0" aluminized turbo-back, single-exit exhaust system for the Ford Excursion 7.3L Power Stroke. This version uses a replacement pipe (muffler delete) for maximum flow, lower EGTs, and a more authoritative exhaust note. Mandrel-bent tubing and OE-style hangers streamline installation and durability for towing and performance builds.

FAQ: WHAT YEARS DOES THIS FIT?

Designed for the Excursion with the 7.3L engine. Coverage commonly lists 2001–2002, while many retailers and the base K4332A kit indicate fitment for 2000–2002 and early 2003 (7.3L). Check your build date and engine (7.3L only) before ordering.

FAQ: DOES IT INCLUDE A MUFFLER?

No. The -RP suffix denotes the muffler replacement pipe (straight-through). If you prefer a muffled version, see Diamond Eye K4332A (muffled kit).

FAQ: IS THIS LEGAL IN MY STATE?

The K4332A family uses a C.A.R.B.-exempt downpipe on the base kit; however, complete vehicle compliance depends on local regulations and configuration. Always verify emissions rules for your state and model year.
