Show original supplier description
The GM 84578424 is a Chevrolet Performance cat-back exhaust upgrade system designed for a noticeable enhancement in sound and performance. Constructed entirely from durable 304 stainless steel, this system ensures longevity and resistance to corrosion. It features 2.75-inch diameter piping leading to a dual-exit muffler configuration, providing a distinct exhaust note. This upgrade system includes the intermediate pipe, exhaust clamps, and all other required mounting hardware for installation. It is specifically designed for use with vehicles equipped with the Ground Effects Package and is compatible with SS models of the Chevrolet Camaro from 2016 to 2024. Installation of this exhaust system may alter the vehicle's exhaust sound profile and requires specific fitment criteria related to factory-equipped ground effects and SS trim levels.
