Turbo Exhaust Sound

Greetings,
I'm considering the purchase of a '12 ZX14 along with a turbo system for the street.
While my snowmobile is turbo'd from the factory, the exhaust exits through a large muffler, and even at full throttle its very quiet.
But, when I look at turbo'd 14s, all I see is a stub pipe for the exhaust to exit through, and no muffler.
Am I missing something here, or is this all that's available to control the exhaust noise?
If this is so, how loud is a turbo'd 14 set up for the street?
I don't mind a little extra noise, but I'd prefer to be considerate to the other motorists on the road, as well as people I pass on the street.

Thanks for your thoughts on this!

Mine is actually not that loud not offensive by any means. You can always put a traditional exhaust on the turbo as well I am sure it will slightly hinder performance but it shouldn't even e noticeable.

Mine is really quiet compared to the sidewinder i used to have before the turbo. But it's still loud enough that you get noticed because the exhaust sounds real cool especially at idle,it has a whirring sound.

OK, just so as I understand both of you correctly, you're not running a muffler at all on you street turbos, right?

Thanks for confirming this!

I'm just having a hard time understanding how a short stub pipe out of the turbo is anything but deafeningly loud.

I just bought a turbo 14 with a full exhaust out behind the turbo. It's super quiet. As in quieter than even my N/A 14 with a Muzzy M14/M10 exhaust and that bike has always been the quietest bike at the track whenever we go.

Thanks everyone, much appreciated!

The next question is, Whose turbo kit to use, and who to use to do the installation and/or tuning?

Also, as this will be a daily-use fun bike, not a track racer, is it necessary to open up the engine to upgrade rods, pistons, etc.

The 2 1/4 pipe and megaphone on my cycle concepts based exhaust is pretty raucous compared to my busa , it has a 2 1/2 pipe 2 1/2 straight through muffler (modified yosh rs3)
and i'm not realy inclined to fit the baffle to the 14 , it looks too restrictive

Sort of need to have at least the appearance of an full exhaust around here , the roadbikes i have played with all have full systems, and race bikes , either a dump for drag or a rear exit big bore for LSR

Depending on your state or countrys laws sometimes its just down to preference

The 2 `1/2 full system on the busa is a little quieter than most NA bike full systems, but deeper .... and it whistles
