Details:

The N1 Evolution Extreme carries forward the proven performance heritage of the iconic N1 muffler, engineered for maximum exhaust efficiency through its straight-through layout design. At its core is an internal hybrid silencer that balances raw power and free-flowing exhaust characteristics with refined sound resonance.

A newly designed titanium muffler tip enhances both function and form, constructed from lightweight rolled titanium, riveted onto a dual-pipe structure. This design not only acts as a diffuser to reduce exhaust temperatures but also delivers a striking heat-gradient finish for a true motorsport aesthetic.
