Description
Upgrade your diesel truck’s exhaust flow, performance efficiency, and aggressive appearance with the Large Bore-HD 5” 409 Stainless Steel DPF-Back Exhaust System, precision-engineered for 2013–2018 Ram 2500 and 3500 6.7L Cummins models. Designed for heavy-duty durability and OE-quality fitment, this system delivers improved airflow, reduced exhaust gas temperatures, and a commanding exhaust tone—without affecting emissions equipment.
Heavy-Duty 5” Stainless Steel Construction
This exhaust system is built from 5” mandrel-bent 409 stainless steel tubing, providing exceptional strength, corrosion resistance, and long-term reliability under extreme heat and towing conditions. Mandrel bends ensure smooth exhaust flow with minimal restriction for optimal performance.
Improved Flow & Performance
By reducing backpressure and turbulence, the Large Bore-HD exhaust allows exhaust gases to exit more efficiently, helping to increase horsepower and torque while lowering EGTs. This makes it an excellent upgrade for towing, hauling, and performance-focused diesel applications.
OE-Style Fit & Leak-Free Sealing
A high-quality OE-style flange is included to provide a complete 360-degree sealing surface, ensuring a tight, leak-free connection. Combined with premium band clamps, this system delivers long-lasting reliability even under high vibration and thermal stress.
Secure, Hassle-Free Installation
The system utilizes all factory mounting locations, along with OE-style bayonet hangers, to maintain precise exhaust alignment over time. These hangers keep the exhaust stable during high heat and vibration, preserving an OE-like fit that won’t shift or loosen.
An included extension pipe allows proper fitment on Crew Cab / Long Bed configurations, making this a true bolt-on installation with no cutting or modifications required.
Massive 6” Black Stainless Steel Exhaust Tip
Finishing the system is a 6” diameter black stainless steel exhaust tip, featuring a laser-cut stainless steel aFe POWER logo plate riveted on for a bold, aggressive appearance that complements the truck’s rear profile.
