After the installation of this product the emission light might come on your dash. To remove it you might need to install the lambda sensor extensions from your existing cat. This is a high quality, 304 grade stainless steel manifold with secondary cat bypass (decat). It is road legal as the 987 has two pairs of cats and this piece only removes 1, thus in conjunction with OE it will pass MOT (although it is ideal for track use). Fitting this part will see a substantial power increase and a little extra noise.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePrimary Diameter = Primary External Diameter 45mm \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCollectors Diameter = Collector External Diameter 54mm\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"ratio ratio-16x9 mb-3 product-iframe\"\u003e\u003ciframe allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen=\"\" data-src=\"https:\/\/youtube.com\/embed\/vfalrcsMVQY?si=v5EfmdDgS9FuHCDI\u0026gt;\" frameborder=\"0\" height=\"560\" loading=\"lazy\" title=\"YouTube video player\" width=\"315\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Dragon","offers":[{"title":"Default Title","offer_id":51430305104138,"sku":"103078","price":899.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0896\/8355\/8666\/files\/5d1092fed9d3afbe4428dcb18b3f55c0-fj.jpg?v=1751376635","url":"https:\/\/dragonexhausts.com\/products\/porsche-987-1-boxster-cayman-decat-exhaust-manifolds-223","provider":"Dragon Exhausts ","version":"1.0","type":"link"}
