{"product_id":"signature-rear-exhaust","title":"Signature Rear Exhaust","description":"The Active Autowerke Signature Rear Exhaust system is engineered to elevate the performance and sound of your BMW E9X N52 325i, 328i, and 330i, model years 2006-2012. Its free-flow design, coupled with 80mm dual exhaust tips, permits a 35-40% increase in exhaust flow compared to the factory setup, thereby minimizing backpressure and unlocking significant horsepower and torque gains. The system is constructed from 100% brushed 304 stainless steel, providing both a visually striking appearance and enhanced longevity.\n\nThis exhaust system produces a refined, sporty tone without excessive drone, thanks to the integrated Active Autowerke Muffler and Noise Cancellation Chamber. It is designed to follow factory-fit specifications, offering a weight savings of approximately 14 lbs over the stock BMW exhaust. Installation requires cutting of the factory pipe, with detailed dimensions and cutting points provided in the instructions. Some models may require welding if the factory pipe is oblong in shape, rather than round.\n\nIt is important to note that this exhaust will only fit the XI (4-wheel drive) and Station Wagon models if purchased with the Active Autowerke N52 Mid Pipe, or if welding is performed to join the exhaust to the stock pipe. For optimal performance and reliability, it is recommended to pair this exhaust with an Active Autowerke Performance Tune.","brand":"Active Autowerke","offers":[{"title":"Default Title","offer_id":52686760804664,"sku":"11-021","price":721.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660178860.webp?v=1784876420","url":"https:\/\/store.motormia.co\/products\/signature-rear-exhaust","provider":"MOTORMIA","version":"1.0","type":"link"}
