The factory converter's dense honeycomb core is one of the largest restrictions in the exhaust, and the turbulence it creates downstream slows flow even further. Removing it lets the turbos exhale freely, so torque arrives sooner, the power curve climbs higher and the exhaust note gets noticeably more aggressive.\u003c\/p\u003e\n\u003cp\u003eEach set is built in-house in the USA from 304 stainless steel with mandrel-bent 3\" tubing, fully TIG welded. The 3.5\" turbine-housing V-band flange is CNC machined from billet stainless, the O2 sensor bung sits in the factory location, and the factory donut-style flange connection is retained, so the downpipes bolt straight up to the stock exhaust or any aftermarket system designed for the factory downpipes.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCatless design for maximum exhaust flow\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 donut-style flange connection; 100% bolt-on\u003c\/li\u003e\n\u003cli\u003eFinish options: Brush (default), Mirror Polish, or high-temp Black Ceramic Thermal Coating\u003c\/li\u003e\n\u003cli\u003eCeramic Thermal Coating rated to 2000°F; lowers underhood temperatures, keeps exhaust velocity up and adds corrosion resistance (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. 16 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\u003eCompetition Series catless downpipe 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\u003e\n\u003cstrong\u003eECU tune (required):\u003c\/strong\u003e removing the catalytic converters will set catalyst efficiency fault codes without software.
