PLEASE NOTE!
Unleash the true potential of your 1998.5-2002 Dodge Ram 5.9L Diesel. This 4" Turbo-Back Exhaust Delete Kit is engineered for maximum performance and sound. The mandrel-bent 409 stainless steel, straight-through design reduces backpressure, lowers EGTs, and delivers a powerful Cummins roar—all while improving throttle response and efficiency.

- 409 Stainless Steel Construction – Offers excellent corrosion resistance and durability in harsh or off-road environments.

- Bolt-On Installation – Utilizes factory-style hangers and includes all clamps and hardware; no welding required.
- Catalytic Converter Delete Pipe – Reduces exhaust backpressure for improved turbo spool and potential performance gains.

Important Notes
- Loud exhaust note—designed for users who want an aggressive sound.
- For off-road use only in many regions. Check local EPA/CARB regulations before on-road use.
- Exhaust tip not included (can be purchased separately).
- Tuner Required for Installation: Installing a Dodge Ram 5.9 Disele delete pipe requires more than just swapping out hardware. When removing of the CAT, SCR, and/or DOC involves removing and eliminating emission related sensors. A tuner is required to prevent any check engine light or diagnostic trouble codes from setting.
