EJ255/257 4-2-1 Equal Length Exhaust Manifold Kit by Tomei
With our ever popular EXPREME exhaust manifolds which is 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.
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.
You will have a new higher pitched racing sound from this isometric design. With 2.5mm thick pipes made from SUS304 stainless steel. The Lost Wax process was used to eliminate cracking from welded weak points and for aiding smoother exhaust gas flow without any interference.
