Product Overview

Most DPF-back systems on the market are simply larger tubing with a polished tip. They improve sound and appearance — but that’s where the engineering stops.

The Sinister Diesel 5" DPF-Back Exhaust System is engineered specifically for 2011–2016 6.7L Powerstroke pickups and delivers both aggressive sound and functional design. Constructed from precision mandrel-bent 409 stainless steel, this system increases exhaust efficiency while maintaining factory emissions components.

Our patent pending Thermal Induction Port design is integrated directly into the tailpipe section. As exhaust exits the system, these precision-cut induction ports draw in ambient air and introduce it into the exhaust stream. This engineered airflow mixing effect helps reduce exhaust outlet temperatures by up to 30% at the tailpipe.

To ensure proper fitment across all pickup cab and bed lengths, minor trimming may be required depending on your configuration. This adjustment is quick, straightforward, and allows for precise final positioning of the system.

Lower outlet temperatures mean less concentrated heat at the bumper, trailer, hitch components, and surrounding areas — giving you more than just sound and appearance.

The larger 5-inch tubing produces a deeper, more aggressive exhaust tone without excessive drone, making it ideal for daily driving, towing, or highway cruising.

Why Choose Sinister Diesel

Many exhaust systems focus solely on diameter and tone. Sinister Diesel engineers additional function into the details. The patent pending Thermal Induction Port design actively helps manage exhaust heat at the outlet — delivering engineered performance, durability, and a finished look that stands apart.
