FAQ

Q1: Does this system retain the factory DPF?

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

Q2: Will this improve horsepower or fuel economy?

Because the DPF remains installed, gains are moderate. However, the 5” straight-through design reduces post-DPF backpressure and may slightly improve throttle response and exhaust efficiency.

Q3: Does installation require cutting the factory exhaust?

Most DPF-back systems are direct bolt-on, though some models may require cutting behind the DPF depending on factory configuration. Basic hand tools are sufficient, but professional installation is recommended for perfect fitment.

Q4: Will this make my truck significantly louder?

You’ll experience a noticeably deeper and more aggressive exhaust tone compared to stock. The DPF and catalytic components help prevent excessive volume or harsh interior drone.
