If you are tired of or bothered by the drone and resonance often caused by GM's 4 cylinder economy mode, also known as their Active Fuel Management (AFM) system, this Corsa exhaust will give you a highly aggressive exhaust note while removing that annoying drone. This full cat-back exhaust is engineered to minimize restrictions, maximize weight savings, and increase the exhuast note of your Corvette C8, all while eliminating resonance from 4 cylinder mode.
