Racer's Lounge - Quietest Muffler?

I'm building an offroading and hunting rig (first gen 4Runner) and am looking for the quietest muffler I can get as to not draw attention. Seeing as how my l33 and ls1 intake has three times the stock horsepower, I'm not worried about any losses.
I always see the reviews for loud exhaust, but never have I seen any for quiet.
Any ideas?

How much room do you have?
Multiple "mufflers" can help, at the track I have heard comments about my car being "quiet" for what it is. It is not outright quiet but rather quiet for a mid 11 second NA car. Exhaust is 3" x-pipe to dual 3" Dynomax Ultraflo which are NOT quiet they are straight through, but then tucked up in the quarter panels I have resonators which are basically just 2.5" glasspacks with turndowns under the bumper. By having multiple straight through "mufflers" I am able to have a pretty free flowing exhaust without an offensive amount of noise. Still louder than you want but if you apply the same idea to a "quieter" muffler I think you could achieve substantial noise reduction without a big power loss.\
You know as an afterthought could you find a used OEM truck muffler on craigslist? The space question becomes a concern again.

Thrush Turbo mufflers are very quiet. My wife's Saleen was loud and droned bad, I tried these and they are too quiet! I don't remember if I got a specific kind, nut it was definitely Thrush and it worked.

this.....i have longtubes, catted y-pipe, and a Thrush dumped before the axle......my car is super quiet, you can barely hear the cam and i have an aggressive 110lsa......the best thing is that thrush mufflers are cheap too, got mine for 28 bucks at Autozone

Find a couple of stock G8 mufflers. They're fuggin terrible, when I had my G8 it was quieter than a freakin police car! I put on some Thrush turbos and it was better, but still quiet, and that was with the reso's removed as well as an X-pipe put in place. But yeah man, if you can find like 4 (if you have room to install 4 under the truck) G8 GT factory mufflers a couple of people are trying to unload, pick them up, those will most likely do the trick for ya.

Post up some pics of this rig, I love 1st gen 4 Runners and the 80's trucks.
I had a magnaflow catback on my old Z28, it wasn't much louder than stock unless you stood on it.
