Cat-Back Exhaust Kit - 05-10 Charger R/T 5.7L

The FLOWMASTER Cat-Back Exhaust Kit for 05-10 Dodge Charger R/T 5.7L is a complete bolt-on exhaust system engineered to replace the factory components from the catalytic converter back. This American Thunder cat-back exhaust system features a 2.5-inch diameter mandrel-bent tubing design with stainless steel construction, delivering improved exhaust flow without requiring suspension or frame modifications. The kit includes 4-inch polished stainless steel exhaust tips that provide a factory-correct appearance while allowing unrestricted gas scavenging from the 5.7L HEMI engine.

Mandrel-bent tubing maintains consistent interior diameter throughout each bend, eliminating the dead spots and turbulence created by crimped factory piping. The stainless steel construction resists corrosion from road salt and moisture exposure, critical for long-term durability in diverse climates. The 2.5-inch diameter is optimized for the fifth-generation Charger's displacement and naturally aspirated configuration, balancing scavenging efficiency with street-manners throttle response. This cat-back design retains the factory catalytic converter and resonator, preserving emissions compliance while removing restrictive muffler components.

Charger R/T owners seeking improved exhaust tone and enhanced engine efficiency without modification to core emissions equipment choose this system for its direct bolt-on installation and proven track record in the Dodge performance community. The kit fits 2005 through 2010 model years and delivers measurable gains in mid-range responsiveness. As a complete system rather than components, all angles, terminations, and mounting points integrate with OEM attachment points, eliminating fitment guesswork. The polished stainless tips complement modern Charger styling while the audible exhaust note reflects the HEMI's displacement and valve activity at cruise and acceleration.
