Corsa Performance Valved Cat-Back Exhaust System for 2023+ Chevrolet Corvette C8 Z06

Description

Upgrade your 2023+ C8 Corvette Z06 with this CORSA Valved Cat‑Back exhaust system — engineered specifically for the 5.5L LT6 V8 and designed to maximize exhaust flow, reduce weight, and deliver a deeper, more aggressive exhaust note. Whether you prefer a refined growl at cruising or a full‑throated roar under load, this system balances performance and street‑friendly manners. With a 3.0″ pipe diameter and high‑quality 304 stainless steel construction, it replaces the restrictive stock cat‑back setup for a more efficient exhaust path and crisp throttle response. For drivers chasing added power, refined sound, and long‑term durability, this exhaust transforms the Z06’s character with a purposeful, performance‑oriented upgrade.

Fitment Notes

• Fits 2023+ Chevrolet Corvette C8 Z06 (LT6 5.5L V8) — both Coupe and Hardtop Convertible (HTC). 

• Uses stock exhaust tips (no tips included) — intended to reuse the OEM rear tips/bezel. 

• OEM NPP valve actuators remain fully functional; system uses CORSA’s custom‑tuned valved mufflers (on NPP variant) and maintains factory driving‑mode behavior when valves are retained. 

• Professional installation recommended; a valve “re‑learn” procedure may be required to prevent Check Engine Lights (CEL) after install.

Included

• Left and right 3.0″ cat‑back exhaust sections (dual rear exit configuration)

• Custom‑tuned CORSA mufflers or muffler‑delete sections depending on chosen part number (valved mufflers for NPP version or straight‑through for track/delete version)

• Braided stainless‑steel flex couplers, solid hangars/rod hangars, mounting hardware, and necessary clamps/weld‑on components as required for a direct bolt‑on replacement

• Installation instructions and support for valve‑relearn procedures to fully integrate with stock NPP valve actuators
