The MBRP Armor Plus 5" Filter‑Back Exhaust System (S61640409) is a high‑quality performance exhaust designed for Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine from 2013 through 2026. Built with heavy‑duty T409 stainless steel tubing, this system replaces the restrictive factory exhaust from the particulate filter back with larger 5" mandrel‑bent tubing to improve exhaust flow and give your truck a more refined performance sound while maintaining daily‑friendly tone.
This single side exit filter‑back system fits most cab and bed configurations (verify specific fitment before ordering) and includes a polished 6" stainless steel exhaust tip for a clean, finished look. The bolt‑on design installs without cutting or welding, using OEM hangers and supplied clamps, making it a straightforward upgrade.
