4'' DPF-Back / Filter Back Exhaust For 2011–2016 Ford F-250 / F-350 / F-450 6.7L Powerstroke

Want a deeper, more aggressive exhaust tone without deleting your factory DPF? Our 4'' DPF-Back Exhaust System is engineered specifically for 2011–2016 6.7L Powerstroke owners who want improved sound, upgraded materials, and better exhaust flow — while remaining DPF-compatible.

This system replaces the exhaust piping behind the factory Diesel Particulate Filter (DPF), maintaining emissions equipment while enhancing tone, durability, and overall exhaust efficiency.

Choose between cost-efficient T409 stainless steel or premium T304 stainless steel for superior corrosion resistance and long-term performance.

FAQ

Q1: Does this system retain the factory DPF?

Yes. This is a true DPF-Back system, meaning it replaces only the exhaust piping after the DPF. Your factory emissions equipment remains intact.

Q2: Will this significantly increase horsepower or fuel economy?

Because the DPF remains in place, performance gains are modest. However, the 4” straight-through design reduces backpressure, which may improve throttle response and overall exhaust efficiency.

Q3: Will my truck be much louder?

Expect a deeper, stronger tone compared to stock. The factory DPF and catalytic components keep the system from becoming excessively loud. Diesel clatter may become slightly more noticeable.

Why Choose DPFexhaust?

DPFexhaust designs premium diesel performance exhaust systems engineered for Powerstroke platforms. Our DPF-back systems deliver improved sound, upgraded materials, and reliable durability — without removing factory emissions components.
