5 Star Rating

Buy in bulk and save


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 factory turbine outlet diameter is small which causes the secondary exhaust pressure to rise. This in turn results in a loss of power, response & unstable pressure. The TOMEI outlet has a larger internal diameter for the best optimization of exhaust flow efficiency & helps reduce the exhaust pressure substantially. If used in conjunction with our TOMEI ARMS turbine. You will see large gains in all aspects of performance. The corrosion-resistant stainless steel material used in manufacturing this product is good with heat resistance up to the flange.

Please note: This kit includes only 3 bolt gasket, does not come with the 5 bolt turbo gasket, we recommend the OEM Nissan 5-bolt turbo gasket found here

The SUS304 material properties have strength, light weight and good rust resistance for both the flange and pipe.
Without impairing mid range torque, the φ73.2mm diameter type delivers best output results at high RPMS.
The high intensity lost wax productions method was used to minimize any exhaust leak from the flange.
High quality pipe bends and production methods were used with superb welding of the flange to deliver the best possible product to you.
Improved turbine response & a decrease in anti- lag pressure whilst on boost.
Highly accurate welding, improved reliability & good looks.


  1. Great

    Great upgrade for running straight exhaust. Very happy I purchased. Get yours now.

  2. Replacement for broken stock outlet

    The elbow fits great and came with everything needed for the install. An open ended wrench and patience will be needed for the install however. The increased response and exhaust flow was well worth it.

  3. Bought this for my 1988 Silvia S12 with S14 SR20DET swap.
