Product Description
DIAMOND EYE K4329A-RP is a 4.0" aluminized turbo-back exhaust system for the 2000–2003.5 Ford F-450 7.3L Powerstroke (automatic, non-catalyst). This kit routes to the passenger-side single exit and includes a muffler replacement pipe for maximum flow and classic turbo whistle, without a muffler.
Mandrel-bent tubing reduces backpressure, improves throttle response, and sheds weight versus restrictive stock piping—ideal for towing and everyday reliability.
FAQ: WILL THIS FIT MY TRUCK?
Designed for 2000–2003.5 Ford F-450 7.3L Powerstroke models with automatic transmission and non-catalyst configuration. If your truck is a later 2003.5+ emissions configuration or uses different transmission/emissions hardware, verify before ordering.
FAQ: DOES THIS INCLUDE A MUFFLER?
No. The -RP variant includes a muffler replacement pipe (straight pipe). If you prefer a muffled version, see the companion part number with muffler (K4329A).
FAQ: WHAT MATERIAL IS USED?
Aluminized steel for a cost-effective blend of durability and corrosion resistance. Stainless options are available in other Diamond Eye part numbers if needed.
