Exhaust Kit for Dodge Ram 2500 (2014-2018) 6.4L

High-Flow Dual Muffler-Back Exhaust Kit for 2014-2018 Dodge Ram 2500 (DJ)

What it Does: The dual muffler-back exhaust kit replaces the restrictive factory single-outlet muffler and tailpipe assembly on the 2014-2018 Ram 2500 to reduce exhaust backpressure, improve scavenging, and deliver an aggressive exhaust tone.

The Stock Dodge Ram 2500 Exhaust Restriction

The OEM exhaust system on the DJ chassis Ram 2500 routes exhaust gases from the 6.4L HEMI (BGE) engine through a massive, heavily baffled factory muffler and a single restrictive tailpipe. This configuration creates excessive parasitic backpressure during high-load hauling and towing conditions. The resulting restriction traps thermal energy near the rear axle assembly, hampers cylinder evacuation during the exhaust stroke, and completely muffles the natural acoustic character of the big-block gas V8.

The Engineering Solution

This dual muffler-back system addresses flow impedance by integrating a two-chamber Flowmaster Super 44 performance muffler with a single 3-inch inlet and dual 2.5-inch outlets. The kit incorporates smooth, mandrel-bent 2.5-inch aluminized steel tubing to minimize internal turbulence and maintain optimal exhaust gas velocity (EGV). Multi-piece, slip-fit tailpipes exit straight back along the frame rails while engineered clearances maintain operational spacing around the OEM spare tire assembly and factory class V receiver hitch.

What's Included

• 1 Flowmaster Super 44 muffler (single 3" inlet, dual 2.5" outlets)
• 2 aluminized mandrel-bent multi-piece 2.5" tail pipes (slip-together)
• 8 muffler clamps
• 1 larger exhaust clamp
• 4 rubber-insulated hangers

Frequently Asked Questions & Fitment Warnings

Does this fit the DJ Ram 2500?

Yes, this is a direct fit for the 2014-2018 Dodge Ram 2500 equipped with the 6.4L HEMI engine and factory single-inlet muffler. Does not fit 6.7L Cummins diesel applications or trucks equipped with dual-inlet factory mufflers.

Is this a direct bolt-on installation?

No, this is a semi-custom kit requiring an experienced installer as pipe fabrication, trimming, or hanger adjustments may be necessary depending on wheelbase and aftermarket suspension clearances.

The Dodge Heavy-Duty Standard

Engineered to handle sustained thermal strain and severe payload demands, this setup delivers the structural durability and lower backpressure mandatory for reliable heavy-duty truck towing.
