With the valves open, it’s 17 dB louder than stock (SAE-measured) and flows 31% better, delivering a sharp climb to redline, a deep bark at wide-open throttle, and crackle on overrun.\r\n\r\nBecause it retains the OEM exhaust valves, you stay in control. Your factory drive modes and exhaust button work exactly as BMW intended, so you can keep things subdued for early mornings and quiet neighborhoods, then open it up when the road calls. Corsa’s Reflective Sound Cancellation (RSC) technology cancels the frequencies that cause cabin drone, so all that aggression never turns into fatigue on the highway.\r\n\r\nThe system is built around a single-run 3.5\" mandrel-bent midpipe for a clean, free-flowing path, and its sound was tuned with downpipes in mind, so it stays dialed in as your build grows. Run it straight through for the rawest, most aggressive note, or add the optional resonator for a more refined tone.\r\n\r\nEvery system is constructed from 304 stainless steel for long-term durability and corrosion resistance, and finished with quad 4.5\" tips in your choice of Polished Slash Cut, Black PVD Slash Cut, Carbon Fiber Polished, or Carbon Fiber Black. The carbon fiber options feature real carbon sleeves over stainless tips for a race-inspired look that pairs perfectly with M carbon trim.\r\n\r\nInstallation is a direct bolt-on using factory hangers, with no cutting or modification required, and every system is backed by the Corsa Limited Lifetime Warranty. Stealth when you want it, savage when you need it, and drone-free the whole way.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eNo Drone, Reflective Sound Cancellation (RSC) Technology\u003c\/li\u003e\n\u003cli\u003eCustom Tuned, Aggressive Exhaust Note, Over 17dB louder versus stock\u003c\/li\u003e\n\u003cli\u003eRobust Valve Assembly and Components are Designed to Last\u003c\/li\u003e\n\u003cli\u003eExtensive Valve Research and Development, Extensive Real World Testing\u003c\/li\u003e\n\u003cli\u003eNo Drone At Cruise Regardless of Valve Position or Mode\u003c\/li\u003e\n\u003cli\u003e304 Stainless Steel Construction\u003c\/li\u003e\n\u003cli\u003eFlows 31% better than stock\u003c\/li\u003e\n\u003cli\u003eDual Walled, 4.5\" Tips\u003c\/li\u003e\n\u003cli\u003eEasy Bolt-On Installation, Plugs Directly into Factory Active Exhaust Module\u003c\/li\u003e\n\u003cli\u003eDetailed Printed Instructions Included, Full-Color Available Online\u003c\/li\u003e\n\u003cli\u003eMade in the U.S.A.\u003c\/li\u003e\n\u003cli\u003eLimited Lifetime Warranty Exhaust, 5 Year Valves\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eExhaust Pipe Diameter\u003c\/strong\u003e: \u003cspan\u003e3.5\"-3.0\"\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eExit Configuration\u003c\/strong\u003e: \u003cspan\u003eDual Rear\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eFlow % Increase\u003c\/strong\u003e: \u003cspan\u003e0.31\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eHazmat\u003c\/strong\u003e: \u003cspan\u003eNo\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eSound Level\u003c\/strong\u003e: \u003cspan\u003eMultiple (Valved)\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eTechnology\u003c\/strong\u003e: \u003cspan\u003eRSC® No Drone\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eTip Finish\u003c\/strong\u003e: \u003cspan\u003ePolished\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eTip Kit: Total Tip QTY\u003c\/strong\u003e: \u003cspan\u003eFour\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eTip Style\u003c\/strong\u003e: \u003cspan\u003eTwin\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eTip: Cut\u003c\/strong\u003e: \u003cspan\u003ePro Series© Slash\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eTip: Edge Style\u003c\/strong\u003e: \u003cspan\u003eDual Walled\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eTip: Outlet Size\u003c\/strong\u003e: \u003cspan\u003e4.5\"\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eTip: Shape\u003c\/strong\u003e: \u003cspan\u003eRound\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eWeight Reduction\u003c\/strong\u003e: \u003cspan\u003e10\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Corsa Performance","offers":[{"title":"Default Title","offer_id":50707898499210,"sku":"COR-21400","price":3099.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/0619\/2778\/files\/0_21400_a_lowres_normalized.jpg?v=1793998715","url":"https:\/\/www.onlyinstock.com\/products\/corsa-21400-3-5-3-0-cat-back-exhaust-with-dual-mode-active-exhaust","provider":"Only In Stock","version":"1.0","type":"link"}
