Frequently Asked Questions
What is the CORSA 14762?The CORSA 14762 is a 2.75-inch Sport valve-back exhaust for the 2014-2019 C7 Corvette Stingray and Grand Sport with automatic transmission and factory NPP active valve, featuring twin 4.5-inch polished quad tips and RSC-tuned Sport-level European character V8 sound.
Does the 14762 work with the factory NPP active exhaust valve?Yes. The CORSA 14762 is designed as a valve-back system that installs downstream of the factory NPP valve, preserving the driver-controlled quiet and sport modes while adding CORSA's RSC-tuned Sport sound in the open position.
Does this fit manual transmission C7 Corvettes?The CORSA 14762 is designed for automatic transmission C7 Stingray and Grand Sport with factory NPP. Manual transmission Corvette owners and those without NPP should refer to CORSA's axle-back fitment options.
What is the difference between 14762 and 14764?Both are valve-back systems for the C7 Stingray and Grand Sport auto with NPP. The 14762 is Sport-level tuning; the 14764 is Xtreme-level with a substantially more aggressive and louder exhaust note.
Is the 14762 drone-free at highway speeds?Yes. RSC technology is calibrated to the C7 LT1 V8's frequency characteristics to eliminate highway drone in Sport mode. In quiet mode, the factory NPP valve provides near-stock sound levels.
Does this require a tune?No. The CORSA 14762 is a bolt-on valve-back replacement. No ECU tune, cutting, or welding is required.
Does the 14762 fit the C7 Z06 or ZR1?The CORSA 14762 is designed for the C7 Stingray and Grand Sport. Z06 and ZR1 owners should refer to CORSA's Z06 and ZR1-specific exhaust fitments.
What is the warranty on the 14762?CORSA provides a limited lifetime warranty on the 14762 against defects in materials and workmanship when purchased from an authorized dealer.
