Has anyone used the Stillen Y-pipe? Any thoughts on it?

looks a lot like the tanube.......without the expansion joints

i wonder how the vibration from the engine will work????

anybody have the stillen y-pipe installed? i assume the expansion/vibration joints in all the other designs the keep the engine vibration and torque from stressing the exhaust brackets..........
