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.


  • High-level of quality using tig-welded SUS304 stainless steel uniting quiet performance with high-power performance gains
  • Matched and manufactured for select chassis
  • Patented Megaphone piping structure to produce excellent torque and throttle response throughout the powerband. This piping design allows for a swirling exhaust gas flow effect that has for years produced proven results.

Please note it does not come with a GT front pipe.

Before completing the installation of the exhaust system with the factory OEM Valve Motor System, follow these steps:

  1. Uninstall the OE Valve Motor: Remove the OE Valve motor from the factory exhaust and disconnect it from the harness connected to the vehicle.

  2. Reset the Valve Motor: Prior to mounting the valve motor on the A'PEXi N1-X Exhaust System, ensure to plug the Valve Motor separately to initiate a factory reset position. This process typically takes around 5-10 seconds to automatically rewind to the reset position. Notably, this reset can be performed without the car being turned on.

  3. Reinstall the Valve Motor: Once the Valve Motor has completed its self-reset, remount it onto the bracket and proceed to install both the Valve Motor and the bracket onto the N1-X exhaust system.

Following these steps ensures proper installation and functionality of the exhaust system with the Valve Motor System.
