Do you guys feather the thottle on cold starts? It really cuts down the noise alot. Even with my supersprint cats, no resonators and E-Race muffs, my exhaust is stupid loud. I can only imagine your set ups. lol.

Greg just start the car and pull feather the throttle and take off slowly. It will quite down in 20 seconds. My neighbors love me at 5am but I try not to take that car to work but once or twice a week.
