More Than One Presilencer, useful?
I've never seen this asked (or found in a search) if there's any advantages to putting two presilencers on (N/A in my case, but info on a TII is also good). I would assume it reduces the sound even more but also reduces the gains produced by the exhaust. Am I on the right track here or just plain retarded (I'm asking for it)? This is fact/opinion/numbers, whatever you want.

You only need two for a full dual NA.
In general the pre-silencer controls the loud, the muffler controls the tone.
For maximum quiet in a straight through system, go with a longer silencer and/or longer muffler.

In a turbo you usually have only one outlet, and the turbine is effectively a pre-silencer.

Yes, aim for a long presilencer with a good diameter. A lot of them you will find tend to be short (14-18") and very narrow, these really don't do you much good. I think the one I use is about 22" by 4.5" and it works great.

do presilencers work well with headers? i had a header that would bolt up to the stock main cat but had a small presilencer(or resonator) from a bonez race pipe cut to fit the 20in gap where the cat would go but i had such a bad leak i could never tell if it was a bearable sound when it all was bolted correctly. i will not put headers back on until i find a way to have a sound not any louder than running a straight pipe to some high flow mufflers.

Here you go. A little expensive but yery nice. Look at the presilencer under the road race exhaust system.
