C7 Corvette Grand Sport CORSA 14776 NPP Axle-Back Exhaust

Upgrade your 2017–2019 C7 Corvette Grand Sport (Automatic) with the CORSA 14776 NPP axle-back exhaust system, engineered to retain full factory valve functionality while delivering a wide, controllable sound range with zero drone.

Constructed from premium 304 stainless steel, the CORSA 14776 features a straight-through, high-flow design paired with 4.5″ quad polished Pro-Series tips for a clean, aggressive OEM+ appearance. CORSA’s patented Reflective Sound Cancellation® (RSC®) technology targets unwanted frequencies, allowing aggressive tone under throttle without intrusive cabin resonance.

With the factory NPP valves retained, this system provides a noticeable sound difference between driving modes — refined and controlled during cruising, and authoritative under heavy acceleration — all while maintaining daily drivability.

Why choose CORSA 14776 for your Grand Sport

  • Factory NPP valve retention for adjustable sound control
  • Variable tone from Sport to Xtreme based on drive mode
  • RSC® technology eliminates highway drone
  • 304 stainless steel construction for long-term durability
  • 4.5″ quad polished tips for a factory-plus appearance

What to expect after installation

  • Noticeably stronger exhaust presence without harshness
  • Clear sound separation between drive modes
  • No cutting or welding — direct bolt-on installation
  • Preserved daily comfort with aggressive capability on demand
  • Made in the USA with a lifetime warranty (5 years on valves)

Fitment & compatibility (read carefully)

  • C7 Corvette Grand Sport: 2017, 2018, 2019
  • Automatic transmission ONLY
  • Factory NPP exhaust REQUIRED
  • Will NOT fit non-NPP vehicles

“The sound difference between modes is exactly what I wanted. Calm when cruising, aggressive when pushed — and zero drone.” – Laura P.
