Smaller mufflers are increasingly being developed and mounted in unusual positions. That's why Arrow has developed the Street Thunder , combining cutting-edge design and technology. Available in stainless steel or carbon fiber, these mufflers feature a diamond shape inspired by the Off-Road program.

To compensate for the reduced volume, Arrow uses high-quality sound-absorbing and heat-insulating materials that have been extensively track-tested. The Street Thunder line is available in homologated versions and in materials such as titanium, aluminum, and carbon fiber, offering superior performance and striking aesthetics.
