DPF-Back Exhaust Systems
What is a DPF-back exhaust?
DPF-back exhaust systems are installed after the DPF system to ensure 50-state legal emission status. The DPF-back exhaust is designed to reduce backpressure and improve exhaust flow to increase horsepower and fuel economy.
Will a DPF-Back Exhaust void warranty?
Since these systems do not modify or remove any emissions components, they are considered an aftermarket exhaust and will not void your factory warranty. In fact, you are protected under Federal Law via The Magnuson-Moss Warranty Act.
