The hugely popular FULLMEGA N1+ has been reborn.
"Revision" is a race-spec exhaust system redesigned into a street model that complies with JASMA standards.
The name is, HYPER FULLMEGA N1+ Rev.
- Hyper Full Mega N1 Plus Rev -

It was extremely difficult to create a bullet-shaped tuning exhaust system that met the JASMA standard in a satisfactory way for a race-spec exhaust system. However, we couldn't let go of the idea of ​​"what we wanted to make."
An exhaust system that is simply equipped with the "safety" of JASMA standards does not "really" look like a real exhaust system.
The key issue this time was how to create a flavor that would allow users to enjoy the true essence of the exhaust system, in a way that is unique to Kakimoto.
While meeting the JASMA sound quality standards, it has the torque required for low and mid-speed driving on the street, and the quick response and high power at high RPMs make for a more racy ride. "The HYPER FULLMEGA N1+ Rev." is now complete for those who want to drive more aggressively on the street.

What is important for an exhaust system used in racing is that it emphasizes high revolutions and how well it can bring out the engine's characteristics.
However, in order to thoroughly pursue exhaust efficiency, the volume is extremely loud.
It is illegal to use such a racing exhaust system on a sports car that is driven on the street. Even if it could be used, it would be difficult to use due to the engine specifications.
The most important role of an exhaust system is to maximize the engine's performance. Sports cars that run on the street need an exhaust system that matches the engine's specifications.
The current "HYPER FULLMEGA N1+ Rev." was designed to achieve the highest specifications possible to fully demonstrate the performance of a street-spec engine.
Emphasis was placed on improving power and response at high revolutions, as well as ensuring torque at low and mid-speed ranges without compromising ease of handling on the street.
The option of using a removable inner silencer to muffle the sound was ruled out because the use of an inner silencer would create excessive exhaust pressure, sacrificing the car's inherent performance at high speeds.
If you drive a car without an inner silencer, which is designed with an inner silencer in mind, the volume cannot be controlled to a legal level, and although the car will perform better at high RPMs, it will be very difficult to handle at low and mid-speeds.
The design overcame these challenges through the use of an original power reducer, internal combustion engine structure, and a sound-absorbing system using an intermediate muffler.
The large diameter main pipe and internal combustion engine structure improve exhaust efficiency, increasing power and response at high revolutions, and the power reducer and intermediate muffler properly control exhaust pressure to achieve torque at low and mid-range speeds, ensuring high performance and effective noise reduction.
The result is a high-spec model that is ideally suited for more racy, aggressive driving on the streets.

By adopting a power reducer and internal combustion engine structure that ensures the torque at low and mid-speeds required for street use and achieves power response at high revolutions, the volume meets JASMA standards without the need for an inner silencer.
In order to achieve the power required for the high RPM range required on the street, the sound volume is kept at the very limit of the JASMA standard.
The company's internal standard for close-range exhaust noise is 98db for vehicles that were manufactured before the 1998 noise regulations, and 93db for vehicles that are subject to noise regulations. (*Varies depending on the model.)
Since it complies with the more reliable JASMA standards, you can enjoy the unique racing sound of Kakimoto Kai on the streets with peace of mind.

The style is bullet-shaped, reminiscent of a racing exhaust system. The simple design is accented with the red "Kakimoto Kai" lettering, giving it a tough look.
In addition, the diagonal rise emphasizes the racy look. The adoption of the diagonal rise makes the bending angle of the main pipe shallower, which not only improves the style but also the exhaust efficiency.
The shiny main pipe and muffler are made of stainless steel, which is not only stylish but also has excellent durability and quality.
In addition to the materials, Kakimoto Kai's unique ingenuity has been incorporated into each part to increase durability.
For example, Kakimoto Kai's original power reducer and noise reduction using internal combustion engine structure not only reduces noise to within JASMA standards and ensures high performance, but also contributes to increased durability.
When using an inner silencer for soundproofing, excessive exhaust pressure is applied when the silencer is installed, causing hot exhaust gas to build up and water vapor in the exhaust gas to accumulate, placing a great strain on the inside of the silencer. By adopting a power reducer and internal combustion engine structure, the appropriate exhaust pressure is maintained, reducing the strain on the inside of the silencer and greatly improving durability.
