Well I know MNL_ICE took the resonator off and it noticeably louder already.
To be honest you don't need it to be louder than it is, unless you want cops and others to really hear you better. Everytime I got pulled over in my STOCK C63 the cops have said "I heard you go by!" and the last one said, "Keep In Mind Your Car Is Loud."
It's your choice but I wouldn't advise making it louder, however put in M, turn your audio off, open the windows, and drive that beast on an open road! You will see that its loud enough.....lol

Hmmm, good post, thank you. I think I might keep them on then.

I'm thinking about doing the 2nd cat delete and leaving the resonator in as well, just had a few questions.
Any CEL problems?
How much were you guys charged for this? I'm assuming they get rid of the 2nd cat and put like a pipe in its place? Or do you just remove it?
What does this do for warranty? I go to my dealer whenever I can to take advantage of the free car washes, would the sound difference be that noticeable to them under regular driving conditions?
I'm assuming some cutting and welding will be done, but aside from a few aesthetics, it's completely reversible? Any change in sound once undone?
Typically, what kind of gains (if any)?

does anyone have a video of just the secondary cat delete? the resonator delete might be too loud for me...
also are there any droning issues when you do theses mods?
@drawde, i removed the resonator on my range rover sport and had no problems with the dealer and they did notice the sounds difference, i know its not mercedes but i figured they wouldnt really care either...

When I had my 03 X5 4.6is I had put on a Eisenmann Race Exhaust from Germany. It was direct bolt on to the resonator and transformed my 4.6 into a monster. It was very very loud and throaty. Anyways when I took it to Prestige BMW the Service Manager mentioned it to me but said it would only be an issue if you had a CEL due to a O2 sensor. Regardless I had complete faith in Eisenmann considering the exhaust cost me $2500 that it would never throw a CEL. Till the day I traded it in for my E46 M3 never an issue arose.

Well, to answer one of my own questions, I asked someone in Service at my dealer and I was told removing my 2nd cat would void my emissions warranty.
Now I guess the question is (other than finding another place to get service), do I really care? What's covered under emissions?
