The S68 uses two primary and two secondary catalytic converters. This complete set replaces the factory primary converters with 200-cell high flow metallic catalytic converters and deletes the secondary converters. The lower cell count means larger cells that exhaust gas passes through far more easily, and the metallic core tolerates higher temperatures than the factory ceramic core, so you gain horsepower, torque and spool while keeping catalytic converters in the system.\u003c\/p\u003e\n\u003cp\u003eBuilt in-house in the USA from 100% 304 stainless steel with mandrel-bent 3\" tubing and 100% TIG welds. The 3.5\" turbine-housing V-band flange is CNC machined from billet 304 stainless, the O2 sensor bung sits in the factory location and the brackets are laser cut and TIG welded with stainless rod, so installation is 100% bolt-on with no compatibility issues with the factory exhaust or an aftermarket system.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e200-cell high flow metallic catalytic converter in each primary section\u003c\/li\u003e\n\u003cli\u003eReplaces the primary sections (high flow catted) and deletes the secondary catalytic converters\u003c\/li\u003e\n\u003cli\u003eMandrel-bent 3\" piping with a smooth transition into the exhaust\u003c\/li\u003e\n\u003cli\u003e100% 304 grade stainless steel construction\u003c\/li\u003e\n\u003cli\u003e100% TIG welded, manufactured in-house in the USA\u003c\/li\u003e\n\u003cli\u003eCNC machined billet stainless 3.5\" turbocharger V-band flange\u003c\/li\u003e\n\u003cli\u003eCNC machined stainless O2 sensor bung in the factory location\u003c\/li\u003e\n\u003cli\u003eLaser-cut stainless brackets TIG welded with stainless rod\u003c\/li\u003e\n\u003cli\u003eRetains the factory slip-on style connection; 100% bolt-on\u003c\/li\u003e\n\u003cli\u003eFinish options: Brush (default), Mirror Polish, or high-temperature Black Ceramic Thermal Coating\u003c\/li\u003e\n\u003cli\u003eCeramic Thermal Coating lowers underhood temperatures and keeps exhaust gas velocity up (black only)\u003c\/li\u003e\n\u003cli\u003eHigher peak horsepower curve and earlier, stronger torque curve\u003c\/li\u003e\n\u003cli\u003eSharper throttle response and faster turbo spool\u003c\/li\u003e\n\u003cli\u003eCompatible with factory or aftermarket exhaust systems\u003c\/li\u003e\n\u003cli\u003eTrack tested durability\u003c\/li\u003e\n\u003cli\u003eShipping weight: approx. 24 lb\u003c\/li\u003e\n\u003cli\u003eLimited Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSports Series high flow catted primary downpipes and secondary downpipes (complete set) in the selected finish\u003c\/li\u003e\n\u003cli\u003eAll hardware required for complete installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eECU tune (required):\u003c\/strong\u003e removing or replacing the factory catalytic converters will set catalyst efficiency fault codes without software: \u003ca href=\"\/products\/s68-jb4-tuner-for-2025-g90-g99-bmw-m5\"\u003eBurger Motorsports JB4 Tuner – BMW M5 (G90\/G99, S68)\u003c\/a\u003e.\u003c\/li\u003e\n\u003cli\u003eNo additional hardware is needed; all installation hardware is supplied by Evolution Racewerks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEvolution Racewerks does not publish an installation guide or video for this part.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/pages\/contact-us\"\u003eContact Speed Logic\u003c\/a\u003e for installation support or fitment questions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNot CARB exempt.
