my current setup is causing a lot of vibration and rattling during cold starts, other than that it sounds great once its warmed up. im trying to decide if i want to midmount some glasspacks or just put the stock mufflers on. the only thing i'm worried about is the glasspacks wont get rid of the vibration/rattling. i watched some clips of the stock cans with o/r h and it sounds pretty damn good, but i'm afraid it'll be too quiet. what do you guys think?
