A'PEXi - N1 Evo Extreme (Axleback) - Lexus IS250 / IS350 (2006~2013)
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.
Premium TIG-welded SUS304 stainless steel construction, delivering both durability and performance gains while maintaining a refined sound level.
Patented Megaphone piping structure optimizes torque and throttle response across the power-band, utilizing a unique swirling exhaust gas flow effect that has been proven through years of performance results.
