This set of 2 mod changes that. By machining anti-surge style ports into the compressor cover and fitting a custom billet insert, the factory turbo starts producing a clear, high-pitched whistle and stronger spool note the moment boost builds.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eNothing else about the turbo is altered. Airflow, lag, reliability and boost control remain exactly as BMW intended. No software changes are needed. The only thing that changes is how the car sounds when you put your foot down.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eMade for the OEM twin turbos in the G80\/G81 M3, G82\/G83 M4 and G87 M2. Aftermarket inlet pipes help the new sound come through more clearly, but the mod works fine on a completely stock setup.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"auto\"\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003eSharp, high-pitched turbo whistle and strong spool note under boost\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003ePrecision CNC-machined ports with custom billet insert\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003eZero impact on airflow, lag, or reliability\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003eNo retune or supporting mods required\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003eWorks on completely stock G8X setups\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003eDirect fit for factory S58 twin turbos\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003eAftermarket inlet pipes recommended for maximum sound\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003ePermanent, non-reversible modification\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hengye","offers":[{"title":"Default Title","offer_id":49438458151156,"sku":"S58G8XT51R","price":819.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/2663\/1156\/files\/e2de7698cddbb514bf8cddd9904abe08.jpg?v=1789877010","url":"https:\/\/pentaautoworks.com\/products\/pa-t51r-mod-for-bmw-s58-g8x-oem-turbos-g80-g81-m3-g82-g83-m4-g87-m2","provider":"PENTA AUTOWORKS","version":"1.0","type":"link"}
