Made it home with my new ML63!
1) Any noticeable smell from not having cats?
2) How is the sound?
3) How as install - 1 hour at a shop? I believe just one gasket needs to be replaced (if you wanted to) and the rest is bolt-on.
4) how's the tune?
However, I like the changes you're making and it revitalized my interest in doing some mods. Ordered AMG side skirts Friday because I really haven't liked the running board look since I bought it.

Also installed a red carbon start stop button.
The new sub is an MB Quart MS1-204 dual 4 ohm. The factory sub ohmed out at exactly 4 ohms per coil, this new sub ohms out at 3.4 ohms per coil. This means this sub will draw slightly more power out of the factory amp as well as cause slightly more heat possibly.
Removal of factory sub.
Comparison of factory sub and MB Quart.
Here is the jumpers taped up and the factory enclosure filled with poly-fill.
You will have to use a pair of dykes or a file to knock off this tab above my finger, it's the alignment pin for the factory subwoofer.
What's the purpose of the poly-fill? Better base response (I'm not an audiophile)?
