A'PEXi N1 Evo Extreme Exhaust | 23+ Integra Type S DE5

Fits:

• 2023+ Acura Integra Type S (Hatch DE5)

Optional GT front pipe sold as a bundle, or reuse your stock/existing front pipe. If you're running the factory OEM valve motor system, it needs to be reset before mounting to the N1-X: unplug it from the factory harness, then plug it in separately on its own for 5-10 seconds to let it self-reset (car doesn't need to be running), then remount it to the bracket and install onto the exhaust.

_______

The N1 Evolution Extreme builds on A'PEXi's proven N1 muffler platform, using a straight-through layout for genuine flow efficiency alongside an internal hybrid silencer that balances power with a controlled, functional exhaust note rather than raw volume. Lightweight titanium tips are rolled and riveted onto a double-pipe structure that acts as a diffuser, reducing exhaust temperature at the tip while giving that heat-gradient titanium look.

The patented megaphone piping structure creates a swirling exhaust gas flow that A'PEXi has used across their lineup for years specifically to improve torque and throttle response through the full powerband, not just peak numbers. All TIG-welded SUS304 stainless steel construction, matched and manufactured specifically for the DE5 chassis rather than a generic universal fit.
