The N1 Evolution Extreme is based on the proven performance basics of the N1 muffler which emphasizes optimum,  exhaust efficiency utilizing a straight-thru layout design. Equipped with an internal hybrid silencer uniting power and free flowing characteristics with effective functional sound resonance. 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.
