Exhaust Kit for Dodge Ram 1500 (2009-2012) 3.7L

High-Flow Dual Muffler-Back Exhaust Kit for 2009-2012 Dodge Ram 1500 (DS)

What it Does: The dual muffler-back exhaust kit replaces the restrictive factory single-outlet assembly on the 2009-2012 Dodge Ram 1500 to reduce exhaust backpressure, improve scavenging, and deliver an aggressive exhaust tone.

The Stock Dodge Ram 1500 Exhaust Flow Restriction

The OEM exhaust system on the DS platform paired with the 3.7L PowerTech V6 relies on an overly baffled, high-restriction factory muffler and press-bent routing. This OEM configuration induces turbulent exhaust flow, elevated backpressure, and thermal retention under load. Additionally, standard crush bends reduce functional cross-sectional diameter, choking engine efficiency and muting the truck's acoustic character.

The Engineering Solution

This kit upgrades the system with a genuine two-chamber Flowmaster Super 44 muffler featuring a single 3-inch inlet and dual 2.5-inch outlets, utilizing internal delta-deflector plates to accelerate gas velocity and scavenge cylinders efficiently. Fabricated from heavy-duty aluminized steel, the slip-fit 2.5-inch multi-piece tail pipes utilize smooth, mandrel-bent geometry to maintain constant internal cross-sectional diameter around the rear axle. The pipes exit parallel to the frame rails, cleanly clearing factory receiver hitches and standard-sized spare tires across all cab and bed wheelbases.

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
