This manifold is built to bolt in place of the factory manifold. Instead of utilizing the stock internal wastegate valve this will allow much finer control of boost by using two external wastegates.
Since there isn’t much room for gates a Tial 38mm MVS or a Turbosmart 40mm wastegate are the only ones we offer these for.
WASTEGATES NOT INCLUDED
These manifolds are built to make your FA Powered WRX more responsive and make controlling boost much easier.
Product is built per order so there are NO REFUNDS OR RETURNS
