Item Description

The NA Sports Feel Has Evolved To An All New Level.

The 1st Version design had the targets of “Sharp throttle response”, “Sports engine enjoyment” & “True race exhaust sound”. The new version 2 design has all those target aspects met with the additional target of increased power gains. The designs were made and time painstakingly tested both on the engine bench Dyno in a controller environment and on the car in real life uses in the Z Masters race series in Japan. With these tests we found to have excelled in additional performance gains from the previous 1st Version model.

■THE MOST POWERFUL ENGINE IN THE Z-MASTER RACE SERIES!!

EXTENSIVE REASEARCH & DELVEOPMENT

1. LENGTH COMPARISON TEST

The equal length shows smooth torque results mid rage and the unequal length shows more power up high in the power band. The equal length also delivers a much better race engine sound. The unequal length shows room for power gains up top with more R&D.

EQUAL LENGTH PROTOTYPE

UNEQUAL LENGTH PROTOTYPE

STANDARD LAYOUT EQUAL LENGTH CHOSEN

2. OPTIMUM DISTANCE TO MERGE SECTION

The 3 Test Stages of finding the optimum distance to the merge section.

(1) Comparison of 370mm and 620mm
The 620mm length design showed the power band peaked around the 4000 RPM area.

(2) Comparison of 90mm, 240mm and 370mm
The shorter 90mm and 240mm showed the power decrease before the 6000 RPM range.

* From the various test results obtained we decided with the 450mm length which is in between the 370mm~ 620mm area.

(3) Additional tests was done with length ranges between 370mm to 620mm at 400,450. 500 & 550mm sizes to find any extra gains.

　From the additional extensive testing we found the 450mm delivered the best results.

EQUAL LENGTH PROTOTYPE 620mm

THE 450mm LONG TYPE WAS CHOSEN

3. PIPE DIAMETER & MERGE SECTION

Increasing the exhaust pipe diameter is will increase performance gains but too large will cause power loss. We found after numerous tests that the φ42.7mm size made best results.

φ42.7→φ45.0 BENCH DYNO TEST EXHAUST

These test results showhow we tested
and why we chose the exhaust manifold product designs of equal length
φ42.7mm L=450mm.

■ STOCK COMPARISION

With the best layout design there was an additional 0.5kg weight savings gained from our new design.

■ THERMAL PROTECTION

With the new performance design layout it is hard to use the thermal bandage to control the heat in the engine bay. So for added performance gains we have also added a Titan Bandage and thermal protector and flexible thermal tube cover. These accessories are all included in the kit and help reduce performance robbing heat.

■ EXHAUST FLOW OPTIMZED

For the optimum performance layout the pipe bends are designed to maximize exhaust flow efficiency. The merging section joint angles have all been flow tested and with the smooth pipe layout, performance is maximized with this bolt on kit.

■THE EXPREME PERFORMANCE

RESPONSE
Instant throttle response which delivers a real race engine experience and feel.

TORQUE
Improved mid range torque. More torque gives your 3500cc engine more grunt and more fun.

POWER
More power in higher RPM range which makes a big difference between the factory settings and our EXPREME upgrade.

SOUND
The 1.5mm thin 304 stainless steel will deliver the harmonics of a dry racing sound. The feeling will exceed the famous Ferrari F355.

LIGHT WEIGHT
The super lightweight design flange and 1.5mm pipe were adopted for the optimum performance benefits. The end result was a reduction of 9.1kg. (When combined) the lighter weight will affect the cars handling with a lighter front end will make it easier whilst turning.

■ TRACK BRED

The Z33 350Z will shows its true performance capability when you use the TOMEI EXPREME exhaust manifold & straight front pipe combination.

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
