Cat-Back Exhaust System 09-21 Ram 1500 5.7L

The FLOWMASTER Cat-Back Exhaust System for 09-21 Ram 1500 5.7L is a bolt-on performance upgrade designed to improve exhaust flow and enhance the distinctive sound signature of your full-size truck. This stainless steel cat-back system features a 3-inch diameter pipeline with a dump-style exit, delivering noticeable gains in both acoustic character and engine breathing without requiring engine tuning or computer recalibration.

The 3-inch diameter construction maintains optimal scavenging velocities through the exhaust system, reducing backpressure while keeping exhaust velocity in the sweet spot for the 5.7L Hemi engine. Stainless steel construction provides corrosion resistance in harsh environments—essential for trucks exposed to salt air, winter road treatments, or frequent towing. The dump-style exit eliminates the factory muffler and resonator, creating the aggressive exhaust note that enthusiasts seek while freeing up undercarriage real estate. Installation is straightforward bolt-on work at the axle and frame mounting points, making this a popular choice for owners who want tangible results without deep custom fabrication.

This system is engineered for 1500 series Ram owners running the 5.7L V8 engine who prioritize both audible presence and underhood efficiency. Whether towing, highway cruising, or spirited acceleration, the improved flow characteristics provide measurable responsiveness. The kit covers the critical post-cat section of the exhaust path, making it compatible with factory or aftermarket catalytic converters and ideal for owners seeking a complete bolt-on solution without full custom welding or fabrication work.
