Product Description

The aFe Power 49-43090-P Large Bore HD DPF-Back Exhaust System is engineered for modernFord Super Duty trucks equipped with the 6.7L Power Stroke V8 diesel engine from 2017-2025.Constructed from mandrel-bent 409 stainless steel with a 5" diameter, this high-flow exhaustsystem replaces the restrictive factory exhaust behind the diesel particulate filter (DPF) toenhance exhaust flow, reduce backpressure, and lower exhaust gas temperatures for improvedthrottle response, torque, and overall performance.

The system exits with a polished 6" slash cut tip and utilizes intercooled tailpipes that helpmanage heat at the rear exit. Heavy-duty band clamps and OE-style bayonet hangers secure theexhaust using every available factory mounting point, providing stability under load and highvibration conditions. While cutting behind the DPF is required for installation, all includedhardware and precision-formed tubing are designed to simplify the process. Ideal for dieselowners seeking increased flow, improved sound, and a robust stainless steel exhaust upgrade.
