Sorry, one more question I forgot. Has you're vette had to pass emissions tests since you modded the exhaust system? How loud is it without a muffler?

Hey there, I'm am gauging some interest in you're car. I have a few questions, first one, what size are you're C6 wheels? Second, has there been any history of repairs or mechanical issues? The picture you posted with you're instrument cluster, the keys are in ACC mode with the door open? It shows a service engine soon light, had to be sure .
