I got LTH on mine - Quiet mode helps with cold start in morning but it’s much louder than stock quiet cold start. I live in apartment complex has to leave for work at 4:30am haven’t had any issues with my neighbors complaining. I’ll see if I can get some sound clip for that next time.72 whp increase is something that I might consider. How quiet is quiet mode (valves closed) with the long tube headers? (Starting the Mustang in the morning)
