FUJITSUBO Technology

  • Japanese

Fujitsubo's spirit is to "produce the highest quality products". This has not changed since Fujitsubo was first established in 1931. This spirit does not only pertain to creating highly efficient and high quality exhausts and manifolds, but it also applies to our customer's satisfaction. This is the reason Research and development is performed with people, motor vehicles, society, environment etc, all thought as one, to create a product through diversity.

Fujitsubo is continuously pursuing advanced technologies. A chassis dynometer, 1/3 octave band sound analysis device, and other specialized equipment are utilized to accumulate important data from the latest technologies. Increased productivity through advanced 3D laser processing machines and automated pipe benders. Strict quality control with CCD cameras, image analysis software, and 3D CAD. Cumulative performance analysis through actual vehicle testing. This type of research, development, and production structure has led to the Fujitsubo patented exhaust manifold (Pat. No. 1320379).

Joint

High-precision processing achieves smooth exhaust, strength and light weight against turbulence and leakage of exhaust flow due to steps, and play and looseness due to vibration. High quality is ensured by special welding technology.

Straight Layout

Through research is performed on each application to find the most efficient and free flowing path for the exhaust from the main pipe to the exhaust tip.

Lightweight Press Mold Flange

A lightweight press mould flange has been implemented in the product dissection department to research lightweight technology. Intense strength of t=2.3mm has been achieved (some products not included).

Lost wax manufacturing method

Light weight with precise product quality and effective thinning.

Donut type Joint

Stress on the exhaust system has been successfully decreased through high quality flex joints. Vibration from engine and chassis are absorbed by the flex joint reducing stress to the exhaust system.

Dedicated lightweight bracket

The lightweight brackets used in Super Ti, Legalis Super R, Power Getter, RM-01A, etc. ensure sufficient strength and durability.

Lightweight hollow pipe stay

Lightweight hollow pipe stay with header. We realize weight saving more than 50% in comparison with solid wood and prevention of support rubber coming off.

Stay mounting part for thin material

The concentration of stress is prevented through the base plate.

Main Silencer

In order to maximize the high efficiency and noise reduction effect, it is set for each model.Punching pipes, stainless steel demisters, glass wool, cut wool, etc. are used as sound deadening materials. It achieves a sporty exhaust sound with improved exhaust efficiency and unique sound tuning.

Straight structure

Reactive structure

Dual pipe system structure

Face Process / Weld

Surface processing

Change the surface for each product or place of use such as polishing and hairline. Beautiful surface treatment is proof of high quality.

SUS304 stainless weld

By TIG welding, it has good strength and durability while maintaining its beautiful appearance.
