2015 LML Duramax deleted, aero muffler

4 inch turbo back exhaust system with an aero turbine 4040xl muffler. We really like the sound of these. They are available in a loud or a quieter option. Most customers prefer the 4040xl ( quieter )

Love that the video starts mid-rev and ends with a honk lol

Any chance at more videos of this setup?

What model of aero is this? That's the sound I'm looking for.

Dpf and cat still intact? I'd love if it actually tames a true straight pipe exhaust down to that level.

Do you have more sound clips of it full throttle

[charliehollis]

Does it take the drone noise out of the cab

[Jerdel]

Which version is this? Quieter or louder and is this on a stock LML?
