Exhaust Kit for Dodge Ram 1500 (2009-2018) 5.7L

High-Flow Dual Muffler-Back Exhaust Kit for 2009-2018 Dodge Ram 1500 (DS)

What it Does: The Dual Muffler-Back Exhaust Kit replaces the restrictive factory single-exit exhaust on the 2009-2018 Ram 1500 to relieve exhaust backpressure, improve scavenging efficiency, and clear factory frame components.

The Stock Dodge Ram 1500 Exhaust Restriction

From the factory, fourth-generation DS chassis trucks equipped with the 5.7L HEMI and a single-inlet setup are choked by an oversized, heavily baffled OEM chambered muffler. This massive assembly creates severe exhaust gas turbulence and thermal retention, forcing exhaust pulses against excessive backpressure during high-load hauling and towing. Furthermore, factory crush-bent tubing limits velocity, restricting volumetric efficiency and deadening the natural V8 engine note.

The Engineering Solution

This kit upgrades the exhaust architecture starting at the muffler inlet with a Flowmaster Super 44 chambered muffler, utilizing a high-velocity 3-inch single inlet that splits into dual 2.5-inch outlets. The tailpipes are manufactured from mandrel-bent aluminized steel to maintain a constant internal diameter throughout every bend, avoiding the flow bottlenecks of compression bending. The multi-piece slip-fit configuration routes parallel to the frame rails, engineered specifically to clear the factory spare tire and OEM receiver hitch under full suspension travel.

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
