The oversized tips use an inverted clamp neck: the clamp seats inside the sleeve rather than at the tip's outer neck, allowing a longer visible sleeve length while hiding the hardware completely from view. Symmetric quad arrangement, Dinan's signature straight-cut tip profile. No coding, no permanent modification required.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e+\u003c\/strong\u003e Computer-controlled exhaust valves retained — quiet at low speed, open at high load\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e 4.5\" (114mm) black ceramic laser-engraved tips with inverted clamp neck\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Hidden interior clamp for clean, unblemished installation\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Symmetric quad arrangement, straight-cut Dinan tip profile\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e BMW F97 X3 M \/ F98 X4 M fitment (S58)\u003c\/p\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":51268700766454,"sku":"DNND660-0086-BLK","price":2699.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2674\/6278\/files\/06a14295bfb923456da128211c980991L.jpg?v=1784135580","url":"https:\/\/autotecknic.com\/products\/dinan-free-flow-axleback-exhaust-black-tips-bmw-f97-x3m-f98-x4m","provider":"AutoTecknic USA","version":"1.0","type":"link"}
