FEATURES

High Efficiency 4-1 Type

We introduced the high efficiency 4-1 as against the STD 4-2-1. The exhaust efficency of the standard exhaust manifold is not perfect. But Tomei 4-1 type exhaust manifold has high efficency. You could see the change of dramatically driving feeling.

Not-Equal Length Design

The complete equal length is good for the exhaust intervention but reduce the turbine performance and increase the exhaust resistance. Contrary to that, the not-equal length exhaust manifold can lead the efficiency of other cylinders. Tomei design the not-equal length.

Great Expansion of Bore Size of Support Pipe

Tomei enlarged the bore size of support pipe φ60 from the STD one φ42.7. This diameter of support pipe will show the great performance at the boost up or turbine replacement.

Dry Racing Sound

We design not-equal length same as STD that is remained the boxer sound. The clear sound which got dry further by change to the diameter of the support pipe and the stainless steel quality of the material is pulled out and the good feeling could be obtained at the acceleration.

Ultra High Quality

We design the Lost Wax type strength flange. We are perticular about the welding and exhaust efficiency is improved very much.

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.

COMPARISION WITH STOCK

EXHAUST MANIFOLD Description

PERFORMANCE

TEST MODEL

The Engine Dyno graph on the left shows the overall perforamnce increase throughout all RPM ranges to give the overall improved performance results. This was achived with extensive engine bench testing time from our R&D.

This is the results based on the Z33 (350Z) exhaust manifold (headers) + straight front pipes which brings out the overall higher performance throughout the entire RPM range.

STRIVING for PERFECTION

The Engine Dyno graph on the left shows the overall perforamnce increase throughout all RPM ranges to give the overall improved performance results. This was achived with extensive engine bench testing time from our R&D.

This is the results based on the Z33 (350Z) exhaust manifold (headers) + straight front pipes which brings out the overall higher performance throughout the entire RPM range.

ROAD TEST

All data is logged and tested for accruate testing and attention to detail on the products efficiency for finding the best results.

LIGHTER

Case Example: Lancer Evolution where the exhaust is situated at the front of the car, every bit of weight reduction there helps a lot in improving the handling of the cars cornering characteristics. Every bit helps for you to gain that extra edge over your rivals.

QUALITY

LOST WAX PROCESSED

EXPREME is manufactured from various manufacturing methods combined especially for mass production high quantity. But the flange, bend sections & gathering section are finished off with lost wax processing for superior quality.

The benefits of "Lost Wax" Processing

* Stable High Quality

* High Intensity

* Durable

(Smooth inner walls & killer looks)

Lost wax processed on the gathering section and flange

SUS304 MATERIAL

The EXPREME products are made from stainless steel SUS304 material. It is light weight, has best resistance to corrosion, superior in heat resistance, better exhaust race harmonics, helps increase your cars value.

QUALITY CONTROL

All EXPREME products are screened with strict quality control. Even mass productions our QA levels are high to ensure the best possible product that will be worthy of the TOMEI brand name and guaranteed to meet & exceed all users expectations.

* Main Inspection Points

* Each Section Size

* Flange Quality

* No signs of burr or flash

* No signs of scratches or leaks

* Installation tested

* Weight is checked

* There are more inspection points but each product has different extra points addressed.
