S4 redline questions
 

Hi all, I've searched and not found a clear answer about the rev limiter on an s4. Does it have one? I would think as a semi modern car it should and have seen posts claiming either fuel/ignition cut from 7600~8200. I know the s5 has a higher redline. I took my car out drifting and on a higher speed corner a glance at the tach showed me in the 7900 reason. Which I promptly stopped and let the car idle for a bit before turning it off. Car still runs fine but I do not want to cut short my fun time by popping a motor due to stupidity. Thanks in advance.

Revving the shit out of it is not going to make you go faster. Just shift when it beeps at you!

How loud is said buzzer? I bought the car with an rb header and straight pipe, so I cannot really hear anything at wot besides the rotary
