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.

  1. 1JZGTE VVT-I Twin Scroll Turbo Manifold 5 Star Review

    This thing is awesome, super stoked when I saw it and took it out the box. The work put into making this manifold is just beautiful, straight tell its good shit and I have the regular elbow down pipe for the stock turbo, so I can not wait and see the performance I will get with the twin scroll manifold. Thank you!
