{"product_id":"chambered-muffler","title":"Chambered Muffler","description":"The Hooker Headers 21729 Aero Chamber Muffler is constructed from durable aluminized steel and features a natural finish. It is designed to improve exhaust flow by 23 percent, increasing horsepower and torque. The muffler utilizes a unique stepped acceleration chamber to increase exhaust gas velocity and maximum flow.\n\nInternal rust is eliminated by a stainless steel perforated plate. An aerodynamic lens directs sound pressure waves into an acceleration chamber and out of the muffler, while a sound absorption chamber eliminates high-frequency sound waves to produce a deep, throaty, powerful sound. A resonance chamber and tuning tube work together to cancel unwanted frequencies and amplitudes, ensuring a consistent and powerful sound that does not change over time.\n\nThis muffler has a single 3-inch offset inlet and dual 2-1\/2-inch outlets. It is specifically noted as a replacement for Camaro\/Firebird 'F-Body' vehicles from 1986-1992. The product is legal for sale or use on emissions-controlled vehicles.","brand":"Hooker Headers","offers":[{"title":"Default Title","offer_id":52688733667640,"sku":"21729","price":241.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687904131.webp?v=1784893979","url":"https:\/\/store.motormia.co\/products\/chambered-muffler","provider":"MOTORMIA","version":"1.0","type":"link"}
