The S63M runs four catalytic converters, two primary and two secondary; these replace the secondary section and leave the primary catalysts (factory or aftermarket) in place. Removing the secondary catalysts raises the horsepower and torque curves and improves throttle response and turbo spool. The secondary downpipes sit after the secondary O2 sensor that monitors the catalysts, and Evolution Racewerks states they do not trigger a check engine light.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMandrel bent 3\" piping\u003c\/li\u003e\n\u003cli\u003e100% 304 stainless steel construction, 100% TIG welded\u003c\/li\u003e\n\u003cli\u003eCNC machined billet 304 stainless flange duplicating the factory flange\u003c\/li\u003e\n\u003cli\u003eStainless O2 sensor bung and laser cut brackets, TIG welded with stainless rod; O2 sensor stays in the factory location\u003c\/li\u003e\n\u003cli\u003eRetains the factory slip-on connection\u003c\/li\u003e\n\u003cli\u003eCompetition Series: catless design for maximum flow\u003c\/li\u003e\n\u003cli\u003eSecondary downpipe section only\u003c\/li\u003e\n\u003cli\u003eUS Spec \/ Non-OPF version\u003c\/li\u003e\n\u003cli\u003eFinish options: Brush, Mirror Polish, or black Ceramic Thermal Coating (rated to 2000°F; reduces underhood temperatures and adds corrosion resistance)\u003c\/li\u003e\n\u003cli\u003eWorks with factory or aftermarket primary downpipes and exhaust systems\u003c\/li\u003e\n\u003cli\u003eMade in the USA, manufactured in-house\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\u003eER Competition Series catless secondary downpipes (pair) 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\u003eSupporting tuning is recommended to realize the performance gain (sold separately).
