The Thunder exhaust range was designed with a diamond-shaped section. The advanced profile makes it possible to reduce dimensions but maintains an equivalent surface area. Increasing the internal volume results in excellent advantages in noise damping and high performance. Internal structure is stainless steel, TIG welding. The internal parts, sections, exit pipe and the rear endcap are designed to allow for the smoother flow of exhaust gases, reducing back-pressure-generated losses. Thunder silencers are available in titanium, and aluminum. Aluminum is available in 2 different finishes: transparent anodized and black anodized (“Dark” version). Rear endcap is stainless steel or carbon fiber.
