The new exhaust system will not be available to owners of Honda GB models until September.
Yoshimura, It won’t be long before Japan releases their GP-Magnum105 Cyclone exhausts. The Japanese manufacturer plans to debut its new slip-on pipe by September of this year. It will be available in three different colors and have a vintage design that will go very well with the classic appearance of the GB.
The slip-on muffler is Yoshimura Japan’s first product of its kind designed specifically for the Honda GB350 and is only one of many that the company has designed for Big H’s other models. The muffler has a cylindrical tube and a stainless steel exhaust tip, which give it an old-fashioned appearance while maintaining its round body. It’s a straightforward layout that works well with the classic appearance of the GB. You may have it in a variety of finishes, including stainless steel, stainless steel with a black carbon finish, and ultimately burnt titanium. Stainless steel is one of the options.
All of the mufflers, regardless of their individual styles, have been approved by the JMCA and will comply with the Japanese car inspection compliances, as well as the Japanese noise rules and the Japanese emissions standards.
After the installation of this system, Yoshimura predicts that both the power and torque outputs would see significant increases. The performance benefits include a reduction in overall weight, boosts in power, and increases in torque. If you get the ultra-light titanium model, replacing the factory exhaust system with this muffler will result in a weight reduction of 1.3 kilos, which is roughly equivalent to 2.87 pounds.
When compared to the GB’s original pipe, which weighed 3.4 kilograms, the Titanium model was able to shave nearly a third of the weight off of it (7.50 pounds). While the figures relating to the reduction in weight were made public, the brand made no mention of the increases in power or torque.
The Yoshimura brand has affixed its characteristic insignia to the tip of the muffler, which has a metal finish and contains embossed accents and textures, to let you know that the pipe in question is manufactured by the company.
The GP-Magnum105 Cyclone is available for the Honda GB350 and can be purchased for $375 (about 50,000 JPY). The phrase “Yoshimura Quality” is printed on the packaging of the item, but Yoshimura also includes a warranty on the goods that are good for two years.
If you want to acquire this exhaust, you will have to wait a little while longer till Yoshimura makes it available to the public for purchase. There is no precise release date indicated; the product is expected to be available sometime between September 2022 and whenever it is.
