Description

The DIESELR Downpipe Back Exhaust Powerstroke 6.7L system is engineered for long-haul strength, better airflow, and superior performance. Designed specifically for 2011–2019 (with slight modifications for 2020-2025) Ford F250 and F350 6.7L Powerstroke trucks, this exhaust delivers real gains in durability and drivability. Built from 16-gauge T409 stainless steel, the mandrel-bent tubing and precision flanges eliminate backpressure, increase exhaust velocity, and improve throttle response. Installation is hassle-free with pre-welded hangers and TorcTite® clamps. Key features include heavy-duty T409 stainless steel construction, full downpipe back configuration, mandrel-bent and precision-welded components, and TorcTite® clamps with all hardware. It is designed for tuned, off-road Powerstroke trucks, providing a deep, throaty sound and noticeable power gains.
