class=\"esp-lead\"\u003eUnleash your C8 RS6 \/ RS7 with our Race Cat-Back Exhaust System! Experience drastic increases in flow and performance with the loudest emissions-compliant exhaust on the market!\u003c\/p\u003e\n\u003cp\u003eFor this exhaust system, our goal was simple: amplify the exhilarating 4.0T exhaust note with a proper \"straight pipe\" cat-back exhaust system. To accomplish this goal, our engineers started by incorporating full 3\" piping from downpipes to tips. We specifically designed this catback with flow in mind to ensure the exhaust would never be a restriction. Compared to the OEM 2.5\" diameter exhaust piping, the 3\" ECS Race Cat-Back offers a significant increase in exhaust flow and expedited exhaust gas expulsion. For exhaust construction, high-quality 304 Stainless Steel was used to ensure long-term corrosion resistance, durability, and weight reduction. Next, an optimized x-pipe was added to aid in exhaust scavenging. This x-pipe further improves the flow of this system and results in substantial horsepower and torque gains. Black chrome RS-style oval exhaust tips are included with the exhaust for OEM+ styling and precise fitment inside the factory diffuser.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cimg src=\"https:\/\/assets.ecstuning.com\/product_library\/1969068_x800.jpg\" alt=\"C8 RS6 \/ RS7 Race Cat-Back Exhaust System\" loading=\"lazy\"\u003e\n\u003c\/div\u003e\u003c\/div\u003e\n\u003cdiv class=\"esp-sec\"\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul class=\"esp-feat\"\u003e\n\u003cli\u003eDual 3\" (76mm) downpipes are designed to adapt directly to factory or aftermarket catalytic converters.\u003c\/li\u003e\n\u003cli\u003e3\" straight-through mid-pipes lead into an optimized x-pipe to increase exhaust scavenging.\u003c\/li\u003e\n\u003cli\u003eX-pipe splits to dual 3\" (76mm) for the tailpipe section.\u003c\/li\u003e\n\u003cli\u003eThe beautifully crafted final assembly is artfully TIG-welded and back-purged for superior durability and the finest appearance.\u003c\/li\u003e\n\u003cli\u003eBarbed exhaust hangers feature 360° hanger stoppers that are TIG-Welded in OE locations for precise location and factory-like fitment.\u003c\/li\u003e\n\u003cli\u003eBlack Chrome RS-style oval exhaust tips feature a laser-etched ECS Tuning insignia for an OEM+ appearance.\u003c\/li\u003e\n\u003cli\u003eStrategically placed slip joints are joined with 304SS Accuseal clamps, providing acceptional adjustability and perfect fitment.\u003c\/li\u003e\n\u003cli\u003eOffers significant weight savings over the restrictive factory cat-back exhaust.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"esp-sec\"\u003e\n\u003ch2\u003eWhat's included\u003c\/h2\u003e\n\u003cul class=\"esp-feat\"\u003e\n\u003cli\u003e3\" (76mm) Downpipes\u003c\/li\u003e\n\u003cli\u003eDual 3\" (76mm) Non-Resonated Midpipe Assembly\u003c\/li\u003e\n\u003cli\u003e3\" (76mm) X-Pipe\u003c\/li\u003e\n\u003cli\u003e3\" (76mm) Tail-Pipes\u003c\/li\u003e\n\u003cli\u003eECS Black Chrome RS-Style Oval Exhaust Tips\u003c\/li\u003e\n\u003cli\u003eM8 Locking Nut (6) - N91130802\u003c\/li\u003e\n\u003cli\u003eExhaust Gasket (2) - 8W0253115D\u003c\/li\u003e\n\u003cli\u003eValve Delete fixture to ensure no check engine light!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"esp-sec\"\u003e\n\u003ch2\u003eProduct Development\u003c\/h2\u003e\n\u003cp\u003eOur C8 RS6 \/ RS7 Race Cat-Back Exhaust System was designed, engineered, tested, and quality inspected by our Research and Development team in our Wadsworth, Ohio facility.
