Corsa's patented RSC (Reflective Sound Cancellation) technology means an awesome full throttle roar yet a quiet, non intrusive and non resonating cruise. Corsa brought it to us first! Two different sounds and four different tip styles are available to choose from. Guaranteed for as long as you own your Corvette, these systems can't be beat for sound, technology, and build quality. They easily bolt right onto the factory system in minutes. Please choose your options carefully below. The Touring Edition provides a crisp, exotic car sound with a quiet cruise and no resonance inside the passenger cabin. It is not recommended for 2001 Corvettes due to the factory pre-cats on all '01 cars which muffle the sound even further. The Pace Car Edition offers a bolder, more aggressive sound during full-throttle and quiet during cruise - and without annoying in-cabin resonance drone associated with other systems.
