we're talking thin washers like 1/16" right?

Yeah, I had some washers that were about 1/16". Maybe slightly larger, but not quite 1/8".

Is the drone worse with DOD on or off?

I have done the washer mod in the past. I preferred just one washer on the bottom bolt but after a day or two I would get sick of the sound. The drone sucked with AFM so I just turned it off. I don't know, it was cool but after hearing other G8's in person with actual exhausts that cost more than 8 cents it just didn't measure up when hearing it from outside the car. Inside it is muffled but outside I could tell that throaty burble just wasn't there. More like exhaust noise and not a defined exhaust note.
I just ordered my Pypes and hope to have them here and installed this weekend. I'll try the J pipe mod that my man JMorris has done because his car sounds awesome with very little cruising drone.

I agree, that's what I've been running since about a month after getting the car. I had a SLP Loudmouth catback system on my previous car (2001 Grand Prix GT) and although I loved the sound, the drone finally got the best of me and I started hating the drone on my ~25 minute commute every day.
On the G8 I pulled out the flanges and have one small washer on each of the 4 bolts. Just enough burble inside the cabin and from the outside/rear-of-the-car, and hardly any drone at all, sans an 1800-1900rpm slight drone when AFM kicks in. That can be fixed with a SC tune though.
I'm quite happy with my washer mod. much more cost effective and honestly has better characteristics IMHO as well (little to no drone, unlike axelbacks/catbacks.)

You cannot strengthen the weak by weakening the strong. You cannot help the wage earner by pulling down the wage payer. You cannot help the poor by destroying the rich. You cannot help men permanently by doing for them what they could and should do for themselves.

But what if Magnaflow gave me the washers,Would that take away some of the guilt! ?
LOL! Good point! Then it would be an "official" mod.
