DIAMOND EYE K4319S-TDRP is a 4.0" T409 stainless turbo-back exhaust system for the 2000–2003.5 Ford 7.3L Powerstroke F-250/F-350. This configuration includes a muffler replacement pipe (straight pipe) and a single turn-down rear exit for reduced backpressure, quicker turbo spool, and a deep, authoritative tone.

FAQ: WILL THIS FIT MY TRUCK?

Designed for 2000–early 2003 (03.5) 7.3L Powerstroke F-250/F-350, all cabs and bed lengths, typically with automatic transmission and non-catalyst factory configuration. Always confirm your build date and emissions equipment before ordering.

FAQ: MUFFLER VS. MUFFLER REPLACEMENT PIPE?

This TDRP kit replaces the muffler with a straight section for maximum flow and a more aggressive exhaust note. If you prefer a quieter system, see the companion kit with muffler (part K4319S-TD).

FAQ: STAINLESS TYPE?

T409 stainless steel tubing balances corrosion resistance with durability for year-round use while keeping weight in check.
