🔇 Built-In Muffler – Flow Without the Drone
Straight-pipe flow with a controlled, daily-drivable sound. No harsh highway resonance.
💰 DPF & CAT Delete – Save Thousands in Maintenance
Eliminate costly regenerations, cleaning, sensor failures, and replacement of the entire aftertreatment system.
🌡️ Lower EGT & Protect Your Engine
Free-flowing exhaust reduces backpressure and lowers exhaust gas temperatures, extending turbo and engine life.
⚡ Faster Turbo Spool & Sharper Throttle
Less restriction means quicker boost response – more power when you need it, especially while towing or climbing.
🛡️ T-409 Stainless Steel – Corrosion-Resistant
2mm thick T-409 stainless outlasts factory mild steel against salt, moisture, and heat. Built for the long haul.

This 6.7 Powerstroke delete pipe with muffler is a 4-inch DPF & CAT race pipe designed for 2011-2019 Ford F-250, F-350, and F-450 Super Duty pickup trucks. It replaces the restrictive factory DPF and catalytic converter section with a freer-flowing exhaust path while adding a muffler for a more controlled sound profile.
For drivers who want a smooth exhaust experience from a straight exhaust pipe but don't want excessive noise inside the car, this is undoubtedly the ideal choice.
The original exhaust system integrates components such as a diesel particulate filter (DPF) and catalytic converter (CAT) to meet emission standards. However, as vehicle mileage increases, a series of problems arise:
For off-road or performance-oriented modifications, these issues often prompt owners to opt for low-resistance DPF removal pipe to improve exhaust efficiency and simplify the exhaust system structure.
Eliminating the original diesel particulate filter and catalytic converter significantly reduces the likelihood of all the aforementioned problems. You will no longer be troubled by frequent regeneration, regeneration interruptions, or regeneration failures. Furthermore, you will avoid the high costs of DPF cleaning, regeneration additives, sensor replacements, or complete aftertreatment system replacements.
Compared to a straight-through exhaust pipe, the built-in muffler effectively suppresses high-frequency noise and high-speed resonance, resulting in a deeper, more resonant, and controllable exhaust note. This is ideal for users who seek performance but prefer a quieter sound.
The 4" straight-through pipe allows hot exhaust gases to flow more smoothly, effectively controlling exhaust temperature and reducing the thermal load on the turbocharger, cylinders, and surrounding components. This extends the lifespan of the engine and turbocharger. Furthermore, with reduced exhaust resistance, the power response when the accelerator is pressed is more direct, especially noticeable during heavy-load starts, rapid acceleration, or hill climbing.
| Comparison Item | Race Pipe with Muffler | Race Pipe (without Muffler) |
|---|---|---|
| Exhaust Flow | Freer than factory | Freer than factory |
| Performance | Greatly reduced back pressure, sharp throttle response | Maximum flow, slightly higher peak output |
| Sound Profile | Deeper and more controlled | Louder and more raw |
| Daily Sound Comfort | More moderated | More aggressive |
| Best For | Buyers wanting flow gains with less harsh exhaust tone | Buyers prioritizing maximum sound presence |
A race pipe with muffler is better suited to buyers who want freer exhaust flow with a more moderated tone.
A non-muffled version is typically chosen by owners who want the rawest exhaust sound possible from a more direct race setup.
