Born from the legendary N1, the A'PEXi N1 Evolution Extreme (N1-X) cat-back prioritizes exhaust efficiency with a straight-through layout and a hybrid internal silencer that balances free-flow power with refined, motorsport-inspired sound. A newly designed, dual-wall titanium tip is rolled and riveted over a double-pipe diffuser structure to help reduce exit temperatures while delivering the signature heat-gradient look.
