Nissan 370Z Forum - View Single Post - Why does the exhaust growl more aggressively for the first few minutes after starting

Mine sounds like a massive exhaust leak and loud when started. I thought it might be the flex piping in the exhaust. As the exhaust gets heated up the flex piping expands sealing itself up.
