they are not in any way good for the street !!!
if you looked at the link on youtube you will have about a 10th of how loud they really are .
the harmonics in the fiberglass helmets make it worse the cabon fiber ones are just a little better but thats pretty much all you hear .
the exhaust is the other thing the noise out of the LS7 with the pipes running down the spot were the right side floor was is the other thing .
after a 2 hour stint your ears are ringing then by the time you all finished with the 24 hour event your ears will ring for the next two days .
it will be good when i finish the paddle shifters holding 12 " wide front tires with one hand as your shifting beats the crap out of you .

the noise your hearing is coming from the way the gears are cut (straight ) and meshing together .
my sports racer does the same thing it too has a 6 speed sequential gear box in it .
gear boxes differ just like LSD's do there are many types of both and they all have there own sound to them . I changed out the wedge lock in my sports racer to a triple lock you still hear the whine of the gears but now you also hear the diff more too .
now don't get me wrong ! i never stated that all sequentail gear boxes have straight cut gears . but the whine you hear like in the video is just about the same whine you hear in my cars they are coming from the gears and diff .

it's not just the cost of the gearboxes thats the bad part because all and all they are only about 9 to 12 K it's all the other crap that you have to also buy and do .
