Tomei began operations in 1968 as a race car tuner in Japan. Over the last 40 years Japan has emerged as one of the leaders in automotive research, racing, and culture. Tomei products have been utilized in nearly every motor sport imaginable. Tomei’s racing heritage means their research and design team have first hand knowledge of the extreme demands racing puts on an engine. Using only the highest quality materials means that Tomei’s products can handle the intense strain and heat a purpose built engine will experience whether it be on the street or the track. Tomei’s attention to detail is second to none. All of their products are thoroughly researched and engineered to achieve optimal efficiency. Because of even miniscule differences in measurements can cause catastrophic engine failure, all Tomei products fall within strict tolerances. Tomei machines all of their engine components to enhance airflow and ensure proper fitment and seal.


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.


- 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 heat shield and thermal protector and flexible thermal tube cover. These accessories are all included in the kit and help reduce performance robbing heat.

- For optimum performance 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.
