definitely makes the cement mixer sound till about 1800 rpm. I dont notice if i have the radio on. Slightly more engine braking and revs slightly faster. There is more chatter from the combo as well. The clutch pedal pushes with much less effort and engages closer to the floor than factory.

well, i am done with the car except for possibly a ts ecu and either jwt or aps turbo.

 

oh, install was 300 in case anyone wondered
