Replacing the standard exhaust particulate filter, it optimises exhaust gas flow from your turbocharged engine for a more involving driving experience, the system offers an OEM-quality fit with enhanced performance and everyday usability. \u003cstrong\u003eThis is intended for off-road use only.\u003c\/strong\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003e\n\u003cbr\u003eHow Does It Improve Your Z4 M40i?\u003c\/h4\u003e\n\u003cdiv class=\"flex max-w-full flex-col gap-4 grow\"\u003e\n\u003cdiv dir=\"auto\" class=\"min-h-8 text-message relative flex w-full flex-col items-end gap-2 text-start break-words whitespace-normal outline-none keyboard-focused:focus-ring [.text-message+\u0026amp;]:mt-1\"\u003e\n\u003cdiv class=\"flex w-full flex-col gap-1 empty:hidden\"\u003e\n\u003cdiv class=\"markdown prose dark:prose-invert wrap-break-word w-full dark markdown-new-styling\"\u003e\n\u003cp\u003eA GPF (Gasoline Particulate Filter) delete reduces exhaust back pressure, which allows your turbocharged engine to breathe more freely. With the restrictive filter removed, exhaust gases exit the turbo more efficiently, improving throttle response and helping the turbo spool slightly faster, benefits that become more noticeable on tuned vehicles.\u003c\/p\u003e\n\u003cp\u003eFrom a performance standpoint, gains on a standard car are modest, but when paired with an ECU remap, a GPF delete can unlock more consistent power delivery and support higher boost targets. Acoustically, the exhaust note becomes louder and more aggressive, with increased turbo noise and sharper overrun characteristics, as the GPF normally suppresses much of the sound and high frequency detail.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch4\u003eTechnical Specification\u003c\/h4\u003e\n\u003ctable style=\"width: 100%; height: 133px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003cth style=\"width: 37.942166%; height: 19px;\"\u003ePIPE DIAMETER\u003c\/th\u003e\n\u003ctd style=\"width: 59.282769%; height: 19px;\"\u003e80mm \/ 3.15″\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003cth style=\"width: 37.942166%; height: 19px;\"\u003eMATERIAL\u003c\/th\u003e\n\u003ctd style=\"width: 59.282769%; height: 19px;\"\u003eT304 Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003cth style=\"width: 37.942166%; height: 19px;\"\u003eFITS TO\u003c\/th\u003e\n\u003ctd style=\"width: 59.282769%; height: 19px;\"\u003eOEM or Milltek Downpipe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003cth style=\"width: 37.942166%; height: 19px;\"\u003eMODEL\u003c\/th\u003e\n\u003ctd style=\"width: 59.282769%; height: 19px;\"\u003e\u003cspan\u003eBMW Z4 M40i G29\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003cth style=\"width: 37.942166%; height: 19px;\"\u003eFITMENT YEARS\u003c\/th\u003e\n\u003ctd style=\"width: 59.282769%; height: 19px;\"\u003e2019-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003cth style=\"width: 37.942166%; height: 19px;\"\u003eFITTING TIME\u003c\/th\u003e\n\u003ctd style=\"width: 59.282769%; height: 19px;\"\u003e1.5 Hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003cth style=\"width: 37.942166%; height: 19px;\"\u003eNOTES\u003c\/th\u003e\n\u003ctd style=\"width: 59.282769%; height: 19px;\"\u003eWhere not supplied use original fittings.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 0, 0);\"\u003e\u003cstrong\u003e\u003cbr\u003e*Please Note: Due to Milltek's huge range of products, on occasion there can be a 3-4 week lead time on exhaust systems.
