Perfect Pipe Size, All Equal Length.
We designed the headers to be the 4-2-1 layout with φ42.7mm, φ45.0mm, φ60.0mm sizes to help extract the absolute maximum from your EJ25 turbine with the 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.
