The Doc Race T4 twin scroll manifold has been redesigned (9/20) to now be a one piece design for ease of installation. It was put to the test by a handful of very high performing race cars before attempting to fit to their test car. With the design it is capable of producing well beyond 1000hp for anyone looking to really push the limits of this platform. The wastegates can be accessed easily without taking out any hot exhaust parts. This will come in handy if you ever need to change springs in your wastegates on the dyno or after hard runs.
