Maximum LS Sound From the Axle-Back Position on the 2005-2008 Corvette C6
The Corsa COR21010 Xtreme Axle-Back Exhaust is a 2.5-inch mandrel-bent T304 stainless steel system for the 2005-2008 Chevrolet Corvette C6 6.0L or 6.2L LS V8. The Xtreme is Corsa's loudest street-legal exhaust note and uses RSC (Reflective Sound Cancellation) technology to eliminate the highway drone that makes cabin noise unbearable on long drives. The COR21010 exits through twin 4.5-inch polished stainless tips and is a direct bolt-on to the factory C6 axle-back flanges.
