A newly adopted muffler tip completes the tail end of the exhaust that serves both purposes of function and form. Constructed with a light weight titanium material rolled and riveted onto a double pipe structure which acts as a diffuser enabling temperature reduction, meanwhile retaining a sporty heat gradation appearance.
