Tomei 421101 Expreme Turbine Outlet Pipe Nissan Skyline GT-R RB26DETT BNR32/BCNR33
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.
An aftermarket exhaust system is one of the most popular purchases for any car enthusiast looking to modify for their vehicle. This is because an aftermarket exhaust increases performance, sound, and is relatively easy to replace. An engine is basically an air pump, the faster you can flow more air through an engine the more power it will produce. A factory exhaust system was not made with peak performance in mind. Factory units are designed to reduce cost, decrease noise, and be easily mass produced, all of these objectives sacrifice performance. Because upgrading your exhaust allows your engine to breathe more freely throttle response is also improved along with horsepower and torque. Last but not least a less restrictive exhaust system will give your vehicle a more aggressive tone over stock.
The factory turbine outlet pipe diameter is small which causes the secondary exhaust pressure to rise. This in turn results in a loss of power, response, and causes unstable pressure. The Tomei outlet has a larger internal diameter for the best optimization of exhaust flow efficiency and helps reduce the exhaust pressure substantially. Using in conjunction with Tomei Arms turbine you will see an even more substantial gain in power. The corrosion-resistant stainless steel material used in manufacturing this product makes it more heat resistant as well as more lightweight. Without impairing mid range torque, larger diameter pipe 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 flange welding to give the best product possible. Tomei’s design not only improved turbine response but it also decreased anti- lag pressure, relieving strain on the engine and turbo system. Finally highly accurate welding improves reliability and aesthetics.
- The light weight SUS304 material is used for strength & anti rust properties.
- The lost wax process helps ensure that exhaust leaks are prevented.
- Manufactured via lost wax process to eliminate the use of welds.
- With the clean look of no welds these part alls then all will look good.
