ok yall can stop telling me about "you shouldnt speed" and if you know, post help, if ya dont, i dont need/want dumb comments

i was doing a 100+ purely to see how fast it could go, it was around a thursday night on the highway about 3am, so almost NObody on the road, i felt it was as safe/open place as any to open it up and see what it could do, that is when i noticed the sound and just wanted to know what that could be. Not saying i drive 100+ every day or everywhere, it was a one time deal just to see what my car can do


and i know its not cuz it cant go faster, it just doesnt seem like it wants to.
