DPF Back

A DPF-back exhaust system replaces the exhaust section from the diesel particulate filter (DPF) to the rear of the vehicle. Designed for diesel trucks and SUVs, this upgrade enhances exhaust tone, improves flow, and often reduces weight—all while retaining the factory DPF and emissions compliance.

Typical DPF-back kits include mandrel-bent tubing, a performance muffler, and polished tailpipe tips. Made from durable stainless steel, they resist corrosion and are engineered for a direct bolt-on fit using factory hangers.

When selecting a DPF-back, confirm fitment for your specific vehicle and consider the sound level you prefer—options range from mild to aggressive. Explore our collection to find the right system for your build.
