C7 Corvette Z06 CORSA Xtreme Axle-Back Exhaust 14766 (Polished Tips)
The CORSA Xtreme Axle-Back Exhaust System 14766 is built for 2015–2019 C7 Corvette Z06 owners who want CORSA’s loudest, most aggressive tuned performance exhaust sound without the cabin drone that normally comes with a high-volume system. If you want an exhaust that’s always “on” with no quiet modes, this is the setup.
Important valve fitment note (Non-NPP + NPP cars): 14766 as designed for cars without factory NPP, but also states it fits Corvettes equipped with NPP and will delete the valve / sound-mode functionality while not causing a CEL.
Why CORSA 14766 is a top C7 Z06 exhaust choice
- Xtreme Sound Level: maximum aggression and presence
- RSC® No-Drone Technology: helps cancel drone frequencies at cruise
- 2.75" axle-back design: optimized flow and sharp throttle response feel
- Quad 4.5" polished Pro-Series tips: dual-wall, slash-cut show-quality finish
- 304 stainless construction: corrosion resistance and long-term durability
- Direct bolt-on installation: no cutting or welding
What to Expect After Installation
- Noticeably louder, more race-inspired exhaust note under throttle
- Clean, crisp CORSA tone that’s “tuned performance” rather than a muddy rumble
- Strong exhaust presence while maintaining better cruising comfort than typical loud systems
- If installed on an NPP-equipped car: expect no more quiet mode (valve function is eliminated)
