■ Exhaust manifold
The basic design is a 4-2-1 layout aimed at increasing torque from medium and low speeds. The assembly part of 4 or 2 pieces is made longer than mass production, and the angle of the confluence part is narrowed to prevent the blow-down phenomenon (exhaust backflow) that occurs at high rotation speed.In addition, a radial shape was adopted for the joint to the first part to increase the exhaust flow velocity.As a result, the torque (power) is improved from low to medium speed to peak.　>> More details
<Main specifications> ・ Specifications: Made of SUS304 stainless steel ・ Pipe diameter: P = Φ42.6 T = Φ54.0 ・ Safety standard compliant product ・ Made by Maxim Works
* Sports catalyzer (catalyst) integrated type for vehicles with chassis number -300001 ~

■ Street sports brake pads
The aim is "deceleration at will".Designed with an emphasis on stable effectiveness during continuous braking, delicate load transfer in cornering, and flexible control of vehicle speed, rather than simply stopping performance.Focus on the amount of change and how to change the coefficient of friction (μ), which constantly changes depending on various conditions such as pedaling force, speed, and temperature.The "transient characteristics of μ" required by sports-oriented drivers realizes a taste that is synchronized with the sensibilities.　>> More details
