{"product_id":"signature-exhaust-muffler-w-80mm-tips","title":"Signature Exhaust Muffler w\/ 80mm Tips","description":"The Active Autowerke Signature Exhaust Muffler Generation 2 is engineered for BMW enthusiasts seeking a performance upgrade for their F22 228i models equipped with the N20 engine. This system is meticulously crafted from 100% polished 304 stainless steel, ensuring durability and a premium finish. It features adjustable, double-walled 80 mm stainless steel tips that are designed for optimal fitment, even with diffusers, and are suitable for coupe, convertible, and sedan body styles.\n\nThis performance exhaust delivers a refined yet aggressive tone, noticeable weight savings (19 lbs vs. the factory 29 lbs), and measurable power gains. On an in-house dyno, a stock 2013 228i with this muffler upgrade achieved an additional 9 RWHP and 13 LB-FT of torque. The system utilizes larger diameter mandrel-bent piping for maximum exhaust flow and a modular v-band clamp design for easier installation.\n\nInstallation of this exhaust system requires cutting the factory pipe, with detailed measurements and instructions provided. Depending on the specific factory pipe shape, welding may be necessary in addition to clamping. The product includes a complete illustrated instruction manual and comes with a two-year limited warranty.","brand":"Active","offers":[{"title":"Default Title","offer_id":52686761558328,"sku":"11-026","price":749.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661655004.jpg?v=1784876427","url":"https:\/\/store.motormia.co\/products\/signature-exhaust-muffler-w-80mm-tips","provider":"MOTORMIA","version":"1.0","type":"link"}
