This stainless steel high-flow downpipe lets you remove the restrictive factory main catalytic converters. CAD simulation streamlined exhaust flow and ensured an even split into two outlets, and many hours of R\u0026amp;D went into perfect fit, smooth flow, and excellent sound. A Y-pipe is included for fitment with the factory exhaust.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSingle 3.5\" race downpipe\u003c\/li\u003e\n\u003cli\u003eDurable 304 stainless steel with laser-cut flanges and a precision-machined v-band\u003c\/li\u003e\n\u003cli\u003eFactory-like placement of O2 sensors\u003c\/li\u003e\n\u003cli\u003eDesigned with the latest 3D scanning technology\u003c\/li\u003e\n\u003cli\u003eExhaust flow simulated in CAD for optimal routing\u003c\/li\u003e\n\u003cli\u003eAggressive sound that really makes the 2.5T scream\u003c\/li\u003e\n\u003cli\u003eNo drone under normal driving\u003c\/li\u003e\n\u003cli\u003e200-cell catalytic converter\u003c\/li\u003e\n\u003cli\u003eOptional driveshaft removal tool available separately\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2018+ Audi 8V\/8Y RS3 2.5T EVO (EA855)\u003c\/li\u003e\n\u003cli\u003e2018+ Audi TTRS 2.5T EVO (EA855)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe Check Engine Light will appear after installation; CTS strongly recommends Stage 2 software, as CEL deletes and emulators are not compatible with these cars.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEmissions disclaimer:\u003c\/strong\u003e This product is not legal for sale or use on pollution-controlled vehicles operated on public roads and is intended for off-road, race, or closed-course competition use only.
