It is listed for cars fitted with an OPF\/GPF particulate filter, in two versions: one to fit the OE axle-back silencers and one to fit a Milltek axle-back.\u003c\/p\u003e\n\u003cp\u003eThe Z-pipe is a 3D-printed crossover pipe in 316L stainless steel, designed to improve the tone of the S58 straight-six. It merges the exhaust pulses from the engine's two exhaust streams, giving a more exotic sound with less rasp while reducing back pressure. Under load the note becomes cleaner and higher-pitched, a sound Milltek compares to the Nissan GT-R (R35); on deceleration you get a deeper rumble and burble. Thanks to 3D printing, it weighs only slightly more than a traditional X-pipe.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Z-pipe crossover, replacing the X-pipe, twin straight pipes or resonated section\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 3D-printed 316L stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersions:\u003c\/strong\u003e SSXBM1422 fits OE axle-back; SSXBM1423 fits Milltek axle-back\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarket:\u003c\/strong\u003e OPF\/GPF models\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in:\u003c\/strong\u003e United Kingdom\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e3D-printed 316L stainless steel crossover\u003c\/li\u003e\n\u003cli\u003eMerges the exhaust pulses for a more exotic sound with less rasp\u003c\/li\u003e\n\u003cli\u003eCleaner, higher-pitched note under load\u003c\/li\u003e\n\u003cli\u003eDeeper rumble and burble on deceleration\u003c\/li\u003e\n\u003cli\u003eReduces back pressure\u003c\/li\u003e\n\u003cli\u003eMinimal weight increase over a traditional X-pipe\u003c\/li\u003e\n\u003cli\u003eVersions for the OE or Milltek axle-back\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW M3 \u0026amp; M4 (G80, G81, G82) S58 3.0 twin-turbo, 2021 onwards\u003c\/li\u003e\n\u003cli\u003eCars fitted with an OPF\/GPF particulate filter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e non-OPF cars (North America \/ rest of world), which need SSXBM1424 or SSXBM1425, or the M2 (G87), which has its own Z-pipe options.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eThe Z-pipe fits in place of the X-pipe, twin straight pipes or resonated section.
