ARTEC T4 Split Pulse Exhaust Manifold - Mazda 13B-REW
A T4 split pulse exhaust manifold for the Mazda 13B-REW in the FD3S RX-7, for single turbo set-ups. The runners stay divided right up to just before the wastegate valve face, and it suits turbos up to a Garrett G40-1150 as well as the Turbosmart 6466, with a single 50mm wastegate flange for steady boost control.
Note: A wastegate larger than 50mm (up to 60mm) needs custom fabrication along the cut line. Installation by a professional is recommended.
