Tried it on my car. My dad's ENT says he has permanent hearing damage from the one weekend we took it to Sebring like that. Put a little bit of muffling on there (quieted it down maybe 5-10%). Now he just avoids the car like the plague 
On the other hand, I have more displacement and less turbo-muffling...

It comes down to personal preference and what you can tolerate. I have run for many years full open and no cat, both on the street and the track.
In the past I ran a muffler in the off season and then pulled it off for the track. In the end I quit bothering.
A Turbo with a Cat is perfectly tolerable on the street (IMO). A naturally aspitrated car with no cat and straight through is a different situation all together

If it is for track use, you may want to check your track for db limits. I run with a car that exhausts under the diver's door. Loud as the dickens when you pass. The drivers are a little hard to talk to for about an hour after a run.

yeah sorry, my friend the other day got blasted by police about no muffler and he went on about emissions and got stuck in my head.
N/A cars with a 2.5" no cat, now thats just loud. a mate had a 33 skyline N/A like that. you could hear it from blocks away.
how about just dumping the exhaust on the ground just a meter past the turbo

Not a good idea on a Turbo, especially a high horsepower one. Turbo's have a tendancy to flame out the exhausts. Side exit is doable.
There are tricks for beating the noise restrictions at tracks, even with full open pipes.
It amazes me that you can get a hard time with loud cars, yet for a Harley, open pipes is almost mandated, and seems accepted by all.
