Description
Transform the sound, performance, and presence of your 2011–2024 Ram 1500 5.7L HEMI with the STILLEN Cat-Back Exhaust System. Engineered to match the power and attitude of the HEMI V8, this system delivers a deep, aggressive exhaust note along with meaningful gains in horsepower and torque—right where trucks need it most.
Rather than focusing on volume alone, STILLEN engineers optimized exhaust flow by reducing backpressure and refining the system layout. The result is stronger low-to-mid RPM performance, improved throttle response, and a confident, muscular tone that brings the 5.7L HEMI to life without sounding thin, raspy, or overly harsh.
Each system is designed, tested, and manufactured in Costa Mesa, California, using premium stainless steel, mandrel-bent tubing, and CNC-machined components. Every bend and cut is checked throughout production to ensure consistent OEM-quality fitment and long-term durability. STILLEN’s industry-leading adjustability allows precise exhaust tip alignment for a clean, tailored appearance once installed.
Available with polished stainless, burnt blue, or carbon fiber exhaust tips, the STILLEN Cat-Back Exhaust lets you personalize the look of your Ram while reducing overall system weight compared to the factory exhaust. The result is a truck that sounds stronger, responds quicker, and looks the part from every angle.
