The Flowmaster Signature Series Cat-Back Exhaust System is engineered for maximum performance, premium appearance, and an unmistakable exhaust tone for 2009–2024* RAM 1500 trucks. Built from high-grade brushed 304 stainless steel, this system provides exceptional corrosion resistance and a refined, high-end finish that stays looking great for years.

Each system is expertly TIG welded, delivering cleaner, stronger, and more precise welds compared to standard MIG welding. Exhaust flow begins through a 3.00-inch inlet pipe entering a TIG-welded 304 stainless steel straight-through Signature Series muffler. The system then exits through dual 2.50-inch mandrel-bent tailpipes that route cleanly through the factory rear bumper cutouts.

Completing the system are two large 4.50-inch PVD-coated black chrome 304 stainless steel tips, offering a custom performance look that pairs perfectly with the exhaust’s deep, aggressive Signature Series tone.

Dyno testing shows gains of up to 16 horsepower and 16 lb-ft of torque at the rear wheels. This cat-back system installs easily using all factory hangers and factory-style connections. All required hardware and installation instructions are included.
