APEXi N1 Evolution-X Exhaust Lexus IS300 / IS350 2021 Axleback with Stainless Tip (Quad Tip)

The N1 Evolution Extreme is an axle-back exhaust system based on the proven performance basics of the N1 muffler, emphasizing optimum exhaust efficiency using a straight-thru layout design. It features an internal hybrid silencer for effective sound resonance and a newly adopted muffler tip. It's constructed with tig-welded SUS304 stainless steel. The tip material is either lightweight titanium (rolled and riveted onto a double pipe structure that acts as a diffuser for temperature reduction, with a sporty heat gradation appearance) or stainless steel. The patented Megaphone piping structure is designed to produce excellent torque and throttle response throughout the powerband by allowing for a swirling exhaust gas flow effect.
