D-MAX Exhaust Manifold (SR) – Improved Version

Our previous manifold earned a reputation for not cracking; this renewed manifold goes further with 3.0mm wall piping for even greater durability. It uses tough SUS304 stainless, the pipes insert all the way into the flanges, and there is no unnecessary heat-inducing reinforcement welding. Developed to support around 450 hp as a direct OEM replacement with a T25 flange, so the turbo is designed to sit in the stock position. The included reinforcement stay keeps flange distortion to a minimum. The SR20DET firing order is 1-3-4-2, so pipes 1 & 4 and 2 & 3 are paired to minimize exhaust interference and merge the pulses more evenly.
