The only way I know to keep it quiet with that horsepower is........................... Dont crank it!
Is there a version without the music?Turbo cars are usually pretty quiet, watch this vid.

If your going with a turbo setup you MUST use a straight through muffler design.
Dynomax Super Turbos are chambered mufflers. And yes, I know it'll cost power. The guy wants it to be quiet and I'm not going to tell him that he can't run chambered mufflers when he absolutely can. Obviously, that's not going to make the most power, but it will be the quietest.

Don't make your opinion sound like a fact. I ran flowmasters and then Superturbos - both chambered mufflers with my incon Twin Turbo kit. Made 420 rwhp at 10 psi. Don't know what it made on 12...
Just buy an electric cutout and run a tiny and junky exhaust. Believe me, electric cutouts are perfect for this. My friend runs one on his turbo grand prix and he picked up 30rwhp with it open....and when its shut, nobody is the wiser. If you ever want to beat on it just flick the switch and instantly you have full power. I think its a win win situation
Damn that's actually a good idea...i never thought of that for a turbo setup...i could run a 3 inch downpipe from my turbo, fit it with a Y at the end and put the cutout on one end and then a typical 2.5 or even 3 inch exhaust all the way out....then sneak around normal with full exhaust, and crack it open for beating on the imports.
Dynomax Super Turbos are not chambered mufflers, they are a turbo muffler design. Perforated tubes that flow the exhaust gases in a specified direction, the sound control comes from the restriction of these tubes...
Flowmaster uses various baffles in a series of stages or "chambers" which control sound by reflecting it off of these baffles. This is an example of a 3 chamber or 50 series flowmaster, the intial first chamber is the one with the angled baffles, the other 2 are the ones that are side by side further down in the muffler.
Its this type of restriction that hinders forced induction performance. the straight-through flow pattern of a turbo muffler is more beneficial
No, it's not an absolute must to run a straight through muffler...but it's best to do it once and be done with it. If he's to buy a muffler now...IMHO it's a must.
That's what I think he needs to know. What's "best" for one person isn't necessarily best for another. He might be willing to give up (a more realistic estimate of) 30-40 rwhp. At that power level it doesn't make a huge difference, especially if you can't get traction on the street, anyway. If he puts making "a sleeper" ahead of "making power," then perhaps something like the superturbos would be "best" for him.
