Each system is made of high-grade T309 (1.4828) Stainless Steel and hand polished to a mirror finish. After extensive research, this specific alloy was chosen for its sonic resonance properties, low weight, and durability which are close to the properties of Inconel (used in F1).\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp align=\"center\"\u003e\u003cstrong\u003eIMPORTANT\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp align=\"center\"\u003e\u003cstrong\u003e*The exhaust system is designed to be installed directly into existing OEM mounting points*\u003c\/strong\u003e\u003c\/p\u003e","brand":"Titansonic","offers":[{"title":"Cat-Back \/ T304 Stainless Steel","offer_id":51033575555236,"sku":"","price":2133.0,"currency_code":"USD","in_stock":true},{"title":"Cat-Back \/ Titanium","offer_id":51033575588004,"sku":"","price":2833.0,"currency_code":"USD","in_stock":true},{"title":"Equal Length Headers \/ T304 Stainless Steel","offer_id":51033575620772,"sku":"","price":2133.0,"currency_code":"USD","in_stock":true},{"title":"Equal Length Headers \/ Titanium","offer_id":51033575653540,"sku":"","price":2833.0,"currency_code":"USD","in_stock":true},{"title":"Axle-Back \/ T304 Stainless Steel","offer_id":51033575686308,"sku":"","price":2133.0,"currency_code":"USD","in_stock":true},{"title":"Axle-Back \/ Titanium","offer_id":51033575719076,"sku":"","price":2833.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/0372\/7524\/files\/1_S8.jpg?v=1750234916","url":"https:\/\/titansonic.com\/products\/audi-s8-stainless-steel-valved-exhaust","provider":"Titansonic","version":"1.0","type":"link"}
