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\u003ch2\u003eDetails\u003c\/h2\u003e\n\u003ch3\u003eMilltek Z-Pipe Upgrade for Secondary Catalyst Bypass, BMW G80 M3 and G82 M4\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eZ-Pipe Crossover: 3D printed 316L stainless.\u003c\/li\u003e\n\u003cli\u003eUpgrade Only: replaces an existing Milltek X-Pipe, resonator or twin straight pipes.\u003c\/li\u003e\n\u003cli\u003eCannot be used on its own.\u003c\/li\u003e\n\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\u003cli\u003ePipe Diameter: 3.00in (76.20mm)\u003c\/li\u003e\n\u003cli\u003eMaterial: 316L Stainless Steel, 3D printed\u003c\/li\u003e\n\u003cli\u003ePart: Z-Pipe\u003c\/li\u003e\n\u003cli\u003eFitting Time: 1.00 hour\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2020 and later BMW G80 M3 and M3 Competition S58\u003c\/li\u003e\n\u003cli\u003e2021 and later BMW G82 M4 and M4 Competition S58\u003c\/li\u003e\n\u003cli\u003eExisting Milltek 102mm mid-pipe or twin straight pipe customers only\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.
