Description
4-2-1 Isometric Design for Optimum Results at High-End RPM
With our ever popular EXPREME exhaust manifolds which are now used throughout the world. Our EXPREME Manifolds have received numerous high appraisals on all aspects of efficiency, durability, and performance gains. Now with this new addition to the EJ25 user family, we now have a manifold specifically to optimize the EJ25 true power output potential.
SPECIFICATIONS:
- Perfect Pipe Size, All Equal Length: We designed the headers to be the 4-2-1 layout with 42.7mm, 45.0mm, 60.0mm sizes to help extract the absolute maximum from your EJ25 turbine with an equal length design. The exhaust pressure is controlled best by this layout & you can see the peak power gains & at high RPM.
- Stronger, More Precise Lost Wax Collector: The Lost Wax process was used to eliminate cracking from welded weak points and for aiding smoother exhaust gas flow without any interference.
- An All-New Boxer Sound: You will have a new higher-pitched racing sound from this isometric design. With 2.5mm thick pipes made from SUS304 stainless steel.
