Exhaust sound, what do you think?

I took the muffler off my MBRP system, is sounds great going down the road now, but when i rev it like in this video, it just doesnt compare to other videos on youtube, what is wrong with my exhaust, it sounds terrible i think. It also easily over revs now.

that vid is just bad distortion you are probably just hearing the variable vanes more now and making it sound like a jet engine getting ready to take off!!!

I think it sounds cool, makes people that don't know better think your truck is going to take off for mach 1 but kinda gets annoying after a while idling though.
