I have a 2015 C7 on order with the performance exhaust (Z51, 3LT, magnetic ride, manual trans plus other goodies). I have driven a C7 and think the exhaust is too quiet and would like to make the stock exhaust louder. Does anyone know if there are any modifications I can do to it like the C6 muffler modification where you cut open the muffler and weld a straight pipe over the perforated one to create a "straight through" design? I had 2008 Z06 and did that modification. It was perfect. Definitely louder than stock but still quiet on the inside when the butterflies were closed. I will also be adding a supercharger to the car in the next 60 days or so. Thanks for your help.
