CORSA Performance Exhausts announced new cat-back performance exhaust systems for the 2011 Dodge Challenger SRT-8 and 5.7L R/T, the Dodge Charger 5.7L R/T and the Chrysler 300C 5.7L. Featuring CORSA's exclusive Reflective Sound Cancellation (RSC) technology, the exhaust systems deliver a bold sound with no interior resonance. Available for both manual and automatic transmissions, CORSA's new Dodge/Chrysler exhaust systems come in two sound levels for today's enthusiasts: the Sport sound level that delivers a robust, aggressive tone, and the more race-inspired, muscular Xtreme exhaust note. The CORSA Dodge Challenger SRT-8 and 5.7L exhaust systems, which feature a dual rear exit design with CORSA's rectangular GTX 2 Tips to enhance the car's muscular appearance, are: • SRT-8 Manual Sport (#14423) • SRT-8 Manual Xtreme (#14424) • SRT-8 Automatic Sport (#14426) • SRT-8 Automatic Xtreme (#14427) • 5.7L Sport (#14428) • 5.7L Xtreme (#14436) In addition, CORSA offers the Charger 5.7L R/T dual rear exit exhaust system with Twin 3-inch Pro-Series Tips in Sport (#14525) and Xtreme (#14522).
