Description Fitment Shipping & Returns

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.

Key Features

  • Complete 4" Turbo-Back Exhaust System – This comprehensive kit replaces the restrictive factory turbo downpipe and the entire exhaust system from the turbo outlet to the tailpipe with a high-flow, straight-through design.
  • Muffler-Free Straight-Through Design – Features a muffler-delete straight-through section for maximum exhaust flow and aggressive diesel sound.
  • 409 Stainless Steel Construction – Offers excellent corrosion resistance and durability in harsh or off-road environments.
  • Mandrel-Bent Tubing – Maintains consistent pipe diameter through bends for optimal flow and performance.
  • 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.

  • Unlock Real Performance Gains

    • Up to +18 HP and +28 lb-ft torque (depending on tune and supporting mods).

    • Reduces exhaust backpressure for faster turbo spool and improved throttle response.

    • Lowers EGTs by up to 200°F, protecting your engine and enabling further tuning.

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.
