1.Design: Every flaw of the OEM header has been addressed and improvised during the development of the Tomei header, resulting in power gains you can feel throughout the powerband of the car. The OEM headers restrict air flow resulting in loss of power and efficiency. Tomei headers do not restrict air flow thus resulting in an increase in power and efficiency.

2.High Flow Piping Design: The flaw of the OEM headers greatly restricts exhaust gas flow after the engine port and before the turbine port, unlike the OEM, Tomei headers are designed with four 45mm diameter pipes from the engine side flange to the collector and smoothly merge into two 42mm turbine flange ports. This piping design greatly improves the exhaust gas flow so as to the power and efficiency of the engine output.

3.Dry Racing Sound: Unequal length piping produces the "boxer sound", you could feel the power and hear the dry racing sound which improving the driving pleasure.

4.Ultra-High Quality: We design the Lost Wax type strength flange. We are particular about the welding and exhaust efficiency is improved very much.

5.Lightweight and Rust Proof: We select SUS304 stainless steel which is lightweight and rust-proof.

6.Easy Installation: We prepared bolts, gaskets, and easy and full instruction manual for installation. Everybody can install.
