??? Installation Instructions
Warranty - Exhaust: Lifetime, Valves: 5 Years
CORSA recommends installation of exhaust be performed by a professional. Due to GM factory tolerances some C8 exhaust systems may require GM valve relearn sequence (valves should be re-calibrated according to GM Document ID 5406413) to mitigate a check engine light. 4 Cylinder mode may exhibit light resonant frequencies. See Installation Instructions for more details. |
