CORSA Valve-Back Exhaust w/ 4.5 in Twin Tips — C7 Stingray & Grand Sport Auto

CORSA's valve-back system for the C7 Stingray and Grand Sport Automatic covers more of the exhaust system than a standard axle-back — delivering a more complete sound transformation. Available in Sport or Xtreme sound levels, with 2.75-inch tubing and 4.5-inch twin tips sized for the LT1's flow demands. CORSA's patented sound technology keeps interior drone lower than most competitors at this output level.

Sport (14764)
Strong, refined exhaust note with CORSA's drone reduction. The better daily driver choice — aggressive under hard acceleration, livable at highway cruise.

Xtreme (14762)
CORSA's most aggressive sound tier. Dramatic, full-system exhaust transformation. For owners who want maximum impact from a complete exhaust upgrade.

Performance Expectations
A valve-back system replaces more of the factory exhaust than an axle-back alone, resulting in a more dramatic and consistent sound improvement throughout the RPM range. CORSA's drone cancellation technology is a genuine differentiator — owners report significantly less highway drone compared to competing systems at the same sound level.
