DPF Back

DPF Back exhaust systems are a popular aftermarket upgrade for diesel vehicles. The original equipment on these vehicles includes a diesel particulate filter (DPF), which is designed to trap soot and other particles to reduce emissions. Over time, this filter can become clogged, leading to reduced engine performance and lower fuel efficiency. An aftermarket DPF back exhaust system replaces the section of the vehicle exhaust after the DPF.

This type of diesel exhaust system is often built with mandrel bent tubing, which provides smooth, unrestricted exhaust flow. The result can be increased horsepower and torque. Many of these kits are constructed from high-quality stainless steel exhaust pipe for durability. While some kits may include a muffler delete for a more aggressive sound, others retain a muffler for a quieter tone. When upgrading to an aftermarket exhaust, it’s essential to check local regulations, as some areas have strict laws regarding modifications to emissions systems.
