Sport-Level LT4 Sound with Matte Black Tips for the C7 Z06 and ZR1
The CORSA 14768 is a 2.75-inch Sport-level axle-back exhaust system built for the 2015-2019 Chevrolet Corvette C7 Z06, Grand Sport, and ZR1 with manual transmissions without the factory NPP active exhaust valve. While the Xtreme-tuned 14766 delivers maximum aggression, the CORSA 14768 offers Sport-level tuning for Z06 owners who want a refined, distinctly more present exhaust note without going all the way to maximum volume. The system exits through twin 4.5-inch matte black PVD Pro-Series tips. Built from 2.75-inch mandrel-bent T304 stainless steel throughout.

Frequently Asked Questions
What is the CORSA 14768?The CORSA 14768 is a 2.75-inch Sport axle-back exhaust for the 2015-2019 C7 Corvette Z06, Grand Sport, and ZR1 with manual transmission and no factory NPP valve, featuring twin 4.5-inch matte black PVD Pro-Series tips and CORSA RSC technology at Sport-level tuning for refined LT4 performance sound.
What is the difference between 14768 and 14766BLK?Both are axle-back systems for the same C7 Z06 platform with matte black tips. The 14766BLK is Xtreme-level tuning for maximum aggression; the 14768 is Sport-level for a more refined, measured performance improvement over stock.
Is the 14768 drone-free at highway speeds?Yes. RSC technology is calibrated for the Z06 LT4's frequency characteristics to eliminate highway drone while delivering Sport-level sound under acceleration.
Does this fit the C7 Z06 automatic or with NPP?The CORSA 14768 is designed for manual transmission Z06 configurations without the factory NPP valve. Automatic or NPP-equipped owners should check CORSA's NPP-compatible fitments.
Does installation require cutting or welding?No. The CORSA 14768 is a direct bolt-on axle-back replacement at factory mounting points. No cutting or welding required.
Is a tune required after installation?No. The 14768 retains factory catalytic converters and does not alter engine management. No tune is required.
Will the matte black tips hold up on track use?The matte black PVD finish on T304 stainless is heat-resistant and durable for street and occasional track use. Sustained high-heat track sessions may affect tip finish over time.
What warranty does the 14768 carry?CORSA provides a limited lifetime warranty on the 14768 against defects in materials and workmanship when purchased from an authorized dealer.
