Product Description
DIAMOND EYE K4354A-RP is a 4.0" aluminized steel cat-back exhaust system for the 2003–2006 Ford Excursion 6.0L Power Stroke. This no-muffler (straight-pipe) configuration reduces backpressure, improves throttle response, and delivers an aggressive exhaust note while retaining the factory catalytic converter location.
FAQ: WILL THIS FIT MY EXCURSION?
Yes—designed specifically for the 2003–2006 Ford Excursion 6.0L Power Stroke (diesel) in a single, rear-exit layout. If your vehicle is stock or uses the OEM-style catalytic converter position, this system is intended to fit.
FAQ: DOES THIS INCLUDE A MUFFLER?
No. The -RP variant replaces the muffler with a straight pipe for maximum flow and sound. If you prefer a muffled version, see the related Diamond Eye K4354A kit.
FAQ: IS IT LEGAL IN MY STATE?
Regulations vary. Some retailers restrict shipping of straight-pipe systems to certain states. Always check local and state laws before purchase and installation.
