TOMEI EXPREME - Equal-Length Headers - EJ20/EJ25

4-2-1 Isometric Design for Optimum Results at High End RPM.

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.
      
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 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.

Ultra High Quality

Lightweight & Rust-Proof

We select SUS304 stainless steel which is lightweight and rust-proof.

Easy Installation

We prepared bolts, gaskets, and easy and full instruction manual for privator. Everybody can install.
