Next, the Super Turbos were removed and the UltraFlos slipped on the H-pipe. On our routine 5-second, 5,000-rpm burnout, the decibels went up to 100. It was a bit too loud, even for this gearhead, especially if I had to drive for an extended period of time. The Ultra Flos blew away the Turbos by dropping the e.t. to an 11.01 at 122.39. That can make the extra noise worth it.
