{"product_id":"304-stainless-cat-back-exhaust-system","title":"304 Stainless Cat-Back Exhaust System","description":"The Stillen stainless cat-back exhaust system is engineered to enhance the performance and sound profile of 2008-2013 Infiniti G37 coupes and 2014-2015 Infiniti Q60 coupes. Utilizing a true-dual design, this system replaces restrictive factory components with mandrel-bent 304 stainless steel piping, optimizing exhaust flow to deliver gains in horsepower and torque across the entire RPM range.\n\nWhen the throttle is pressed, however, the exhaust releases a signature, aggressive growl that complements the vehicle's sporty aesthetic.\n\nThe rear section features a split exit configuration finished with polished dual-wall tips, providing an upgraded look that fills the factory exhaust cutouts.\n\nThis bolt-on upgrade serves as an effective solution for owners seeking a balance between improved performance metrics and a refined, comfortable driving experience.","brand":"Stillen","offers":[{"title":"Default Title","offer_id":52663852204344,"sku":"504402","price":1627.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687715828.jpg?v=1784330162","url":"https:\/\/store.motormia.co\/products\/304-stainless-cat-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
