Built on APEXi’s legendary N1 architecture, the N1 Evolution-X single-exit cat-back prioritizes straight-through flow and responsive power delivery. An internal hybrid silencer tempers resonance for a refined, motorsport-inspired tone, while the newly adopted dual-wall titanium tip is rolled and riveted over a diffuser-style double-pipe outlet to help reduce exit temps and deliver the signature heat-gradation look.
