The Vigor Diesel 4-inch CAT/DPF Delete Racepipe (with Muffler) is ideal for Ram 2500/3500 owners looking to unleash the performance potential of their 6.7L Cummins engine while avoiding the excessive noise of a straight-through exhaust.
This straight-mount mid-section exhaust replaces the original Diesel Particulate Filter (DPF) and Catalytic Converter (CAT) components, features a high-flow 4-inch exhaust pipe, and comes equipped with a high-performance muffler. It delivers all the benefits of removing the DPF—reduced back pressure, lower exhaust gas temperature (EGT), and improved fuel economy—while maintaining a deep, controlled exhaust note.
👉Core Positioning: Easy Upgrade + Noise Control
| Aspect | Before (Stock) | After (Vigor Diesel Racepipe w/ Muffler) |
|---|---|---|
| Exhaust Backpressure | High (restrictive DPF/CAT) | Low (4" straight pipe + low-restriction muffler) |
| Turbo Response | Laggy, sluggish | Quick, crisp spool-up |
| Power Delivery | Muted, restricted | Smooth, responsive, pulls harder |
| Exhaust Temps | Often high under load | Significantly reduced – safer for engine |
| Sound Experience | Muffled, boring | Deep, aggressive, turbo whistle audible – yet comfortable |
| Maintenance Costs | Recurring DPF/DEF expenses | Virtually zero |
✅ Perfect Compatibility
❌ Not Applicable
Important Note: The 2019–2024 Ram 2500/3500 pickups use the same exhaust layout. This racing exhaust is designed specifically for these trucks. Please confirm your vehicle configuration before ordering.
