The Z-Pipe is a 3D printed 316L stainless crossover that merges the exhaust pulses from the S58's two cylinder banks. The result is a more exotic note with less rasp and reduced back pressure. Under load the sound is cleaner and higher pitched, closest in character to the Nissan GT-R (R35). On deceleration the deep rumble and burble are more pronounced. Advanced 3D printing keeps the weight increase over a traditional X-Pipe minimal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\t\u003cli\u003eSecondary Catalyst Bypass: single 102mm (4in) mid-pipe replacing the factory secondary catalyst section.\u003c\/li\u003e\n\t\u003cli\u003eZ-Pipe Crossover: 3D printed 316L stainless, merges the bank pulses for a cleaner, higher pitched note.\u003c\/li\u003e\n\t\u003cli\u003eFits the Milltek Axle-Back: supplied with the correct adapters and chassis brace.\u003c\/li\u003e\n\t\u003cli\u003eDownpipes: fits OE downpipes or Milltek SSXBM1333 \/ SSXBM1334.\u003c\/li\u003e\n\t\u003cli\u003eFor closed-course and competition use only.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\t\u003cli\u003ePipe Diameter: 4.00in (101.60mm)\u003c\/li\u003e\n\t\u003cli\u003eMaterial: T304L stainless mid-pipe, 316L stainless 3D printed Z-Pipe\u003c\/li\u003e\n\t\u003cli\u003eFits: Milltek axle-back\u003c\/li\u003e\n\t\u003cli\u003eFitting Time: 1.50 to 2.00 hours\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\t\u003cli\u003e2023 and later BMW G87 M2 S58\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhy Choose Milltek?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEngineered for the Emotion.\u003c\/p\u003e\n\u003cp\u003eDesigned and manufactured in the UK with 40+ years of performance exhaust heritage.
