Upgraded my CL550 mufflers with one’s from the CL63. I purchased a brand new rear AMG diffuser so the quad pipes could fit. I was skeptical on how it would sound as there weren’t many videos out there that I was able to find that could help me out. So I decided to do it anyways and it was the best decision I made. If you’re looking to get more growl from your Benz, purchase the AMG mufflers online and put them on your car. They are practically plug and play. No drone either. Awesome and cheap upgrade. The car actually responds quicker on throttle response. Feels like it has more power but this probably isn’t true, I’m describing how it feels from the seat of my pants.
