are any of the 350x exhausts similar to stock sound level?

[BIGCRIP28]

i never heard anything but a stock 350x (mine). i have been debating on which one to get for a while now.
i hear you guys say all the aftermarkets are too loud.
could someone rank these from loudest to quietest?

supertrapp
dg krome power
cobra 4 stroke
cobra jet
dg rcm
cobra megaphone

I have the Cobra 4 stroke and it is LOUD. I've had a supertrapp on my 350 warrior and they vary depending on how many disks you put on.
I've heard of guys putting the stock pipe from a 450r on a 350x but I'm not sure how and what benefits there are.

Do the 450R exhaust. I did. Sounds excellent and deep. Put a HRC tip on it and it will really sound good.

How did you get it on there? Custom weld? Any benefits other than sound?
