I am new to this forum and hope someone can help me with a question I have about the 2017 ZL1 I just purchased. I am disappointed in the exhaust sound and volume at lower RPM. I also own a 2017 Shelby GT350, and as a point of comparison it sounds much better. There is an electronic switch on the Shelby that opens the baffles at low RPM. Evidently this doesn't exist on the ZL1. I have set the computer to the most aggressive exhaust setting, and it's still poor. Does anyone know of a performance shop that can permanently open the baffles, or install such a switch on the ZL1? Or does that option even exist? I plan on installing an aftermarket this year.... On that subject, any recommendations? I am leaning towards the Corsa brand. Thanks
