Founded in 1989 in Berea, Ohio, CORSA Performance invented Reflective Sound Cancellation technology. The 14777BLK delivers the same Z06 NPP-integrated Xtreme performance as the polished 14777 with a blacked-out finish suited to blacked-out exterior packages and dark wheel setups. Every system is assembled in the USA from T304 stainless steel with a limited lifetime warranty.
The CORSA 14777BLK is a 2.75-inch Xtreme valve-back exhaust for the 2015-2019 C7 Corvette Z06, Grand Sport, and ZR1 with manual transmission and factory NPP valve, delivering maximum Xtreme sound in open NPP mode and refined character in closed mode through quad matte black PVD 4.5-inch tips.
How does the 14777BLK differ from the 14777?Both are the same Xtreme NPP valve-back with identical fitment and sound character for the Z06 platform. The 14777 uses polished stainless quad tips; the 14777BLK uses matte black PVD quad tips.
Does the 14777BLK work with the factory NPP driving modes?Yes. Sport and Track modes open the NPP valve for full Xtreme output; Tour mode closes it for quieter operation. RSC technology keeps the system drone-free in both states.
Is the 14777BLK drone-free?Yes. RSC technology eliminates highway drone resonance in both NPP open and closed valve states.
Does this fit the Z06 without the factory NPP valve?No. The CORSA 14777BLK requires the factory NPP valve. Z06 owners without NPP should look at the 14766BLK or 14768 axle-backs.
Is installation a bolt-on process?Yes. The CORSA 14777BLK uses factory mounting points and the NPP valve outlet. No cutting or welding required.
Is a tune required?No. The 14777BLK retains factory catalytic converters and does not affect engine management.
What warranty does the 14777BLK carry?CORSA provides a limited lifetime warranty on the 14777BLK against defects in materials and workmanship when purchased from an authorized dealer.
