CORSA Performance 3.0” Cat-Back Exhaust System for 2023–2026 Chevrolet Corvette C8 Z06 5.5L LT6

Product Description

Transform the sound and performance of your Chevrolet Corvette C8 Z06 with the CORSA Performance 3.0” cat-back exhaust system, engineered to deliver an aggressive exotic tone while maintaining a refined, drone-free driving experience.

Built from premium 304 stainless steel, this system features precision-engineered piping, durable flex couplers, and custom-tuned mufflers designed specifically for the high-revving 5.5L LT6 engine. The result is increased exhaust flow, reduced restriction, and a noticeable improvement in sound character without sacrificing everyday drivability.

This system retains full functionality of the factory NPP (dual-mode exhaust) valves, allowing you to switch between quiet cruising and aggressive performance sound depending on your driving mode. CORSA’s advanced multi-path muffler design ensures quiet operation during normal driving while delivering an intense, race-inspired tone under acceleration.

The system is designed as a direct bolt-on upgrade and reuses factory exhaust tips for a clean OEM+ appearance. With measurable weight savings and improved airflow, it enhances both performance and responsiveness.

Two configurations are available, allowing you to choose the sound profile and performance level that best fits your build.
