The reduced restriction directly after the turbochargers helps improve exhaust gas flow while delivering a much stronger exhaust note and increased turbocharger character.\u003c\/p\u003e\n\u003cp\u003eManufactured from \u003cstrong\u003ehigh-quality SS304 stainless steel\u003c\/strong\u003e, the downpipes are engineered to withstand the extreme temperatures generated directly after the twin turbochargers while providing excellent corrosion resistance, strength and long-term durability. The high-flow catless construction removes the factory primary catalyst restriction for maximum post-turbo exhaust flow.\u003c\/p\u003e\n\u003cp\u003eIntegrated \u003cstrong\u003eflexpipe sections\u003c\/strong\u003e help absorb exhaust movement, vibration and thermal expansion, reducing unnecessary stress through the exhaust system while maintaining a performance-oriented flow path. The downpipes are designed around the factory S58 turbocharger and exhaust connection points for vehicle-specific installation.\u003c\/p\u003e\n\u003cp\u003eOriginal oxygen sensors and applicable OEM hardware should be transferred during installation where required. Professional installation is strongly recommended due to the turbocharger connections, oxygen sensor locations and limited access around the factory exhaust assembly.\u003c\/p\u003e\n\u003ch6\u003eKey Features:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eSS304 stainless steel construction\u003c\/li\u003e\n\u003cli\u003eCatless high-flow downpipe design\u003c\/li\u003e\n\u003cli\u003eDesigned for Non-OPF vehicles\u003c\/li\u003e\n\u003cli\u003eS58 3.0L twin-turbo inline-six fitment\u003c\/li\u003e\n\u003cli\u003eCompatible with BMW M3 G80\u003c\/li\u003e\n\u003cli\u003eCompatible with BMW M4 G82 \/ G83\u003c\/li\u003e\n\u003cli\u003eIntegrated flexpipe sections\u003c\/li\u003e\n\u003cli\u003eRemoves restrictive factory primary catalytic converters\u003c\/li\u003e\n\u003cli\u003eMaximum-flow post-turbo exhaust configuration\u003c\/li\u003e\n\u003cli\u003eReduced exhaust backpressure\u003c\/li\u003e\n\u003cli\u003eIncreased turbocharger sound\u003c\/li\u003e\n\u003cli\u003eSignificantly more aggressive exhaust tone\u003c\/li\u003e\n\u003cli\u003eHigh-temperature resistant construction\u003c\/li\u003e\n\u003cli\u003eExcellent corrosion resistance\u003c\/li\u003e\n\u003cli\u003eVehicle-specific exhaust routing\u003c\/li\u003e\n\u003cli\u003eProfessional installation strongly recommended\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003ePackage Includes:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e1 × Pair of SS304 Catless Downpipes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eImportant Notice:\u003c\/h6\u003e\n\u003cp\u003eThis product is intended for \u003cstrong\u003eoff-road, track and motorsport use only\u003c\/strong\u003e.
