{"product_id":"n52-performance-exhaust-header","title":"N52 Performance Exhaust Header","description":"The Active Autowerke N52 Performance Exhaust Header is specifically engineered for BMW vehicles featuring the N52 or N51 inline 6-cylinder engine, including the E82 128i Coupe or Convertible and E9X 325i\/325xi, 328i\/328xi, and 330i\/330xi Sedan, Coupe, or Convertible models.\n\nConstructed from 100% 304 brushed stainless steel with mandrel-bent tubing, this header is built for durability and optimum flow, designed to eliminate restrictions and free up untapped horsepower. It is guaranteed to fit and is test-fitted on an N52 motor jig for quality control.\n\nThis system includes all gaskets needed for installation, valued at a $150 saving, such as six new oval shape gaskets for the exhaust port seal and two fiber gaskets for the header-to-exhaust system connection. Copper locking nuts and mounting bolts with nuts are also provided.\n\nIt will generate a Check Engine Light (CEL) without an Active Autowerke N52 software upgrade. The product is not compatible with RHD (Right-Hand Drive) cars.\n\nDyno results show potential gains of 20+ WHP over the stock manifold, with improved power and torque curves throughout the entire RPM range. A specific example showed a stock 328i Automatic producing 175 WHP \/ 161 WTQ, while the AA Header with a charcoal filter delete reached 198 WHP \/ 179 WTQ, and with the addition of AA software, achieved 207 WHP \/ 192 WTQ.","brand":"Active Autowerke","offers":[{"title":"Default Title","offer_id":52686763819320,"sku":"7159289675861","price":151.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661655065.webp?v=1784876458","url":"https:\/\/store.motormia.co\/products\/n52-performance-exhaust-header","provider":"MOTORMIA","version":"1.0","type":"link"}
