E350 muffler delete
Sound: Heavy drone? Aggressive sound or obnoxiously loud?
Error: does this trigger a light on our instrument panel?
Anything else that I should know that would help me decide one way or another?
Thanks in advance!

1) Location of O2 sensors. I need to find out the placement of the O2 sensors in the exhaust piping. If you remove a resonator that's placed in front of the O2 sensor, you'll definitely be throwing codes. You want to make sure removing of any pipes/resonators/mufflers doesn't interfere with the O2 sensor.
2) Are you planning to keep original OEM tips? Those are mounted along the bumper if you take a look and is not connected to the tailpipe. I'm planning on going with S63 tips and weld them to new piping. I wonder if new tips will require mounting like the OE tips, which is what I'd prefer to keep them in place.
3) Consider doing a resonator delete and possibly an X-pipe before going full muffler delete. I've been looking alot into the E550's, C350's that have done muffler delete's. With an E350, remember that it's not a V8 so you're not getting that impressive roar with a muffler delete. It will just be loud, and possibly with a bit of a whine or rasp! I'm thinking that a resonator delete & X-Pipe combo will free up the air restriction on the E350 and give a decent tone while not being obnoxiously loud. I feel like the E350 (direct injection) has good power and would sound great if it could just breathe a bit better with less restrictive piping.

What you have done is change the configuration of your vehicle without manufacturer's approval, let alone your state DOT/DMV/DPS. May come back to haunt you at trade in, so keep old parts.

I'd love to hear a video or sound clip so we know how it sounds during idle/acceleration both inside and outside the cabin.
Props on getting it done!

No problems, costs ineffective, and sounds nice!
I must say however it does sound more like an infinity but does so in a way where it sounds distinct to the nature of a mercedes benz.
Here is a my channel where i have posted my car pushing some nice revs..
Overall i must say i am satisfied with the way it sounds, but recently (since i have not driven my car for a while) i have been quite annoyed with the drone it produces out of the dual tips.. Until the engine really warms up and clears its throat (cleaner air filters, clear pipes, fresh fluid) i find myself trapped in either the lower gears (higher revs) or higher gears (very low revs)
...but its by no means "obnoxious"

PS- UPDATE, for the most part I'm happy with the sound when driving. Once it's warmed up it sounds great from inside & outside the car (no droning & deeper externally) but at idle it sounds like it's a diesel. Due to eliminating some back pressure (straight pipe instead of X-pipe), it tends to have more of a "putt putt" diesel sound when parked.

@5Hundred, your car sounds great! I'm afraid I wouldn't like the droning inside but sounds aggressive as hell from outside the car!
If you like...it costs less then $70 at a muffler shop. If you don't like...that's cool, Tomato Tomatoe.
