Description
Increase exhaust flow, performance efficiency, and aggressive styling with the Large Bore-HD 5” 409 Stainless Steel DPF-Back Exhaust System, engineered specifically for Ram 2500 and 3500 Cummins diesel trucks. Built for durability and OE-quality fitment, this system delivers improved airflow, reduced exhaust gas temperatures, and a bold exhaust note without compromising emissions compliance.
Heavy-Duty Stainless Steel Construction
This exhaust system is constructed from 5” mandrel-bent 409 stainless steel tubing, providing excellent corrosion resistance, strength, and long-term durability under high heat and heavy-duty use. Smooth mandrel bends ensure unrestricted exhaust flow and maximum performance.
Optimized Flow & Performance
Designed to reduce turbulence and backpressure, the Large Bore-HD exhaust improves exhaust efficiency, resulting in increased horsepower and torque while helping to lower EGTs. This makes it an ideal upgrade for towing, hauling, and high-load driving conditions.
OE-Style Fitment & Secure Installation
The system utilizes factory mounting locations, high-quality band clamps, and OE-style bayonet hangers to maintain precise pipe alignment under high vibration and heat. The bayonet hangers secure the exhaust in place for a long-lasting OE-style fit that does not shift over time.
An included extension pipe ensures proper fitment on Crew Cab/Long Bed configurations, making installation quick and hassle-free with no cutting or modifications required.
Polished Stainless Steel Tip
Finishing the system is a massive 6” diameter polished stainless steel slash-cut exhaust tip, featuring a laser-cut stainless steel aFe POWER logo plate riveted on for an aggressive, premium appearance.
