With the exhaust valves open, the exhaust gasses travel uninterrupted from the front of the system out through the exhaust tips. When exhaust gasses travel into the multichambered rear muffler \/ resonator, they continue uninterrupted and a Helmholtz resonator reduces drone frequences without restricting flow on the open-valve path. With the valves closed, exhaust gasses travel through a sound reduction path via a smaller 2.5” (63.5mm) pipe, reducing volume and allowing the system to act more civilized when needed. Finally the system terminates via oversized 8.23”x4.76” (211x21mm) RS-style oval exhaust tips. The tips feature a diamond black finish and a subtle APR logo for a refined touch.\u003c\/p\u003e\u003cp\u003eFits Audi RS6 21-25, RS7 21-25\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSmooth transitions and straight-through components maximize performance by reducing restrictions.\u003c\/li\u003e\n\u003cli\u003eComplete catalyst-back system including downpipes, extending from the factory catalyst back.\u003c\/li\u003e\n\u003cli\u003ePrecision brackets and slip clamps ensure accurate alignment and hassle-free installation.\u003c\/li\u003e\n\u003cli\u003ePremium T304 stainless steel construction with TIG welding for strength and durability.\u003c\/li\u003e\n\u003cli\u003eStrikes the perfect balance of power, sound, style, and quality for enthusiasts.\u003c\/li\u003e\n\u003cli\u003ePerformance gains of 9 HP and 16 FT-LBS of torque delivered to all four wheels.\u003c\/li\u003e\n\u003cli\u003eValve-controlled rear mufflers dynamically adjust sound based on driving style.\u003c\/li\u003e\n\u003cli\u003eIntegrated Helmholtz resonator minimizes drone and enhances sound quality.\u003c\/li\u003e\n\u003cli\u003eOptimized flow through dual 3.0” piping with quad exits into dual tips.\u003c\/li\u003e\n\u003cli\u003eDual 8.23”x4.76” RS-style diamond black oval tips with APR logo.\u003c\/li\u003e\n\u003cli\u003eFully emissions compliant for worry-free operation.\u003c\/li\u003e\n\u003cli\u003eMandrel-bent brushed piping for a refined finish.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: true\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Unknown\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"APR","offers":[{"title":"Default Title","offer_id":47948442206359,"sku":"aprCBK0050","price":2944.65,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0497\/9697\/2695\/files\/3fa64f3cfe4eaa94c5df3791fcacd794L.jpg?v=1782385378","url":"https:\/\/nlpperformance.com\/en-ca\/products\/apr-21-25-audi-rs6-rs7-c8-catback-exhaust-system","provider":"Next Level Performance","version":"1.0","type":"link"}
