Why CORSA (RSC® No-Drone Technology)
CORSA is known for their Reflective Sound Cancellation® (RSC®) technology. Instead of relying on packing material that can degrade over time, CORSA acoustically targets the frequencies that cause drone—so you get aggressive sound when you want it, without the annoying cabin resonance on the highway.
Key Benefits (Why Z06 Owners Choose 14766BLK)
- Xtreme tone: loud, sharp, and track-inspired under acceleration
- No-drone cruising: RSC® targets drone frequencies at steady RPM
- Black tips: aggressive rear appearance with quad Pro-Series styling
- Direct-fit: bolt-on axle-back design (no welding required)
- Built to last: 304 stainless steel for corrosion resistance
What to Expect After Installation
- A deeper idle and a much more aggressive tone when you get into the throttle
- Cleaner highway behavior versus typical “loud” systems (reduced cabin drone)
- Sharper, more exotic sound character (often described as tuned performance sound)
- A bold rear visual upgrade from the quad black Pro-Series tips
