C7 Corvette ZR1 CORSA Xtreme Axle-Back Exhaust 14766 (2019) – Polished Tips - Black Tips
Upgrade your 2019 C7 Corvette ZR1 with the CORSA Xtreme axle-back exhaust (Part #14766 - 14766BLK) and get the aggressive, track-inspired CORSA tone with RSC® No Drone Technology. This is the go-to setup for ZR1 owners who want maximum volume under throttle without the annoying highway drone that makes long drives miserable.
Sound + Fitment Clarity (No Confusion)
- Sound level: CORSA Xtreme (loudest / most aggressive)
- Valve type: Non-NPP axle-back (no active sound modes)
- NPP cars: Yes, it can fit — you’ll lose Tour/Sport valve control and the factory actuators are typically retained (“hung”) for compliance.
Why CORSA on a C7 ZR1?
- RSC® No Drone Technology: cancels harsh frequencies while keeping the aggressive tone
- Sharp, tuned sound: CORSA is known for a crisp, performance-focused character (not a boomy “muscle” rumble)
- Premium build: 304 stainless steel construction for long-term corrosion resistance
- Direct bolt-on: designed for a clean install with factory-style fit
What to Expect After Installation
- Noticeably louder, more aggressive exhaust note—especially under throttle
- Clean, crisp tone that matches the ZR1’s character
- Highway-friendly cruising thanks to CORSA’s anti-drone tuning
- Great pairing with other airflow mods (intake / headers) if applicable

- Basic hand tools recommended
- Estimated install time: ~1–2 hours
- Professional installation recommended if you want the cleanest valve/actuator handling
