🗒️ 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 will require GM valve relearn sequence (valves should be re-calibrated according to GM Document ID 5406413) to mitigate a check engine light. See Installation Instructions for more details. 

CORSA branded exhaust systems are backed by a Limited Lifetime warranty for as long as you own your vehicle with proof of purchase. (VIEW WARRANTY)
