Twin scroll merge collector creates a turbulent free area for the exhaust gasses to enter the turbine housing in even pulses at high velocities and low pressure drops. The result is an increase in turbine efficiency by 7-8 percent (faster spool, quicker response) and result in fuel efficiency improvements as high as 5 percent.
