Collection: DPF Back Exhaust

Upgrade your diesel truck’s exhaust flow without removing factory emissions component with our DPF-Back Exhaust Systems. Our exhaust only replaces the restrictive pipe after Diesel Particulate Filter (DPF) with high-quality mandrel-bent tubing for smoother exhaust flow and improved durability.

Built using premium stainless steel and precision manufacturing techniques, our exhausts are engineered for direct bolt-on installation with factory mounting points.

Why Upgrade DPF-Back Exhaust?

Enhanced Exhaust Flow

Mandrel-bent tubing minimizes restrictions and helps improve overall exhaust efficiency compared to stock crimped piping.

Durable Stainless Steel Construction

Our exhausts are built from high-quality stainless steel to resist corrosion, road salt, and extreme heat conditions.

Stylish Exhaust Tips

Many systems include large-diameter black coated exhaust tips that give your truck a clean, aggressive rear appearance.

Performance Benefits

While the DPF remains the primary restriction in modern diesel exhaust systems, upgrading the piping behind it still provides several benefits.

Reduced DPF-Back Backpressure

Improved exhaust routing and larger diameter tubing can reduce pressure after the DPF, allowing exhaust gases to exit more efficiently.

Improved Throttle Response

Smoother airflow can help provide slightly quicker turbo response and improved drivability.

Long-Term Durability

Factory exhaust pipes can corrode or deteriorate over time. Replacing them with stainless steel components ensures long-lasting reliability.

Direct Fit Installation

Our filter-back systems are designed as direct bolt-on upgrades for many diesel truck platforms.

OEM-Compatible Fitment

Each system is engineered to work with factory mounting points, hangers, and emissions equipment, ensuring proper alignment and installation.

No Tuning Required

DPF and emissions system remain intact, hence, installation does not require ECU tuning.

Complete Installation Kits

Kit comes with all required components:

• Mandrel-bent exhaust tubing

• High-quality clamps and hardware

• Exhaust tips

• Factory-style hangers

FAQ

Q: Does eliminating the muffler decrease backpressure or hurt performance?
Most modern diesel trucks equipped with a DPF do not have a muffler. The large component before the rear axle is typically the Diesel Particulate Filter itself, which is the main restriction in the system.

Q: My truck already has a straight pipe after DPF. Will a filter-back exhaust make it louder?
Sound differences are minimal. However, upgraded tubing and exhaust tips can produce a slightly deeper and cleaner exhaust tone.

Q: Does this system keep the factory DPF?
Yes. A filter-back exhaust replaces only the exhaust piping after DPF, meaning all factory emissions equipment remains installed and functional.

Q: Will installing a filter-back exhaust increase horsepower or fuel economy?
Performance gains are typically modest because the DPF remains the main restriction. However, reduced backpressure and improved exhaust flow can slightly improve throttle response and exhaust efficiency.

Q: Is installation difficult?
Not at all! Our filter-back systems are designed for simple bolt-on installation using factory mounting locations.
