Exhaust System 2005-10 5.7L Charger/Magnum/300C

The SLP Performance Exhaust System for 2005–2010 5.7L Charger, Magnum, and 300C is a cat-back performance exhaust designed to unlock the full sonic and flow potential of Chrysler's legendary Hemi V8. This stainless steel system replaces the restrictive OEM exhaust with 2.5-inch diameter piping and aggressive 3-inch tips, delivering increased horsepower and torque while producing the aggressive exhaust note that defines the SLP "Loud Mouth" heritage. Complete bolt-on installation requires no welding or cutting, making it a practical upgrade for owners seeking both performance and character.

The 2.5-inch diameter piping increases flow capacity compared to stock 2.25-inch systems, reducing backpressure and allowing the 5.7L Hemi to breathe more freely at higher RPMs. Stainless steel construction resists corrosion and rust, critical for longevity in harsh climates or high-moisture environments. The larger diameter exhaust outlet improves scavenging efficiency and promotes more complete combustion cycles, translating to measurable gains in mid-range and peak power delivery. This cat-back design preserves emissions compliance while eliminating the resonance characteristics of the original system, producing the distinctive Hemi exhaust tone without the factory muffler's acoustic suppression.

This exhaust system is engineered for 2005–2010 Dodge Charger, Chrysler 300, and Dodge Magnum platforms running the 5.7L V8 engine. The complete kit includes all necessary brackets, hangers, and hardware for direct bolt-on installation to the factory catalytic converter. It appeals to owners seeking a straightforward, reversible performance modification that enhances both auditory character and measurable engine output without complex tuning or modifications to other drivetrain systems. Weighing 51.2 pounds, the entire assembly is manageable for professional installation or experienced enthusiasts.
