    As the title describes! made a short video of the new muffler on the m54b30 engine. Not a lot of videos of exhaust mods on this car so I hope this helps someone decide in the future! I love it despite the drone at 2-2.5k rpms. Has a great gurgle when its hot and engine braking! Definitely gave...
