{"product_id":"street-series-at-2-slip-on-muffler","title":"Street Series AT-2 Slip-On Muffler","description":"The Yoshimura Street Series AT-2 slip-on muffler is a premium upgrade for the CFMOTO 450SS (2023-2026) and 450NK (2024-2026) motorcycles. This exhaust system is meticulously crafted with a durable stainless steel construction and features an eye-catching matte carbon fiber end cap and a custom-fit heel guard, enhancing both the aesthetics and performance of your bike.\n\nEngineered to unlock the full potential of the 449cc parallel twin engine, the AT2 slip-on delivers significant power and torque gains. Dyno testing confirms an increase of 6.3% in maximum horsepower and a substantial 10% gain in maximum torque. Beyond the performance benefits, the AT2 dramatically alters the bike's auditory profile, producing a deep, resonant tone that makes the 450SS\/NK sound like a larger displacement machine.\n\nIt weighs considerably less than the stock muffler, contributing to improved overall handling and responsiveness.\n\nThis Yoshimura AT2 exhaust system is proudly designed, developed, and manufactured in the USA. It is declared a \"replacement part\" by the manufacturer. Please note that this product is not CARB approved and cannot be shipped to California.","brand":"Yoshimura","offers":[{"title":"Default Title","offer_id":52664155832632,"sku":"19450BP520","price":639.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687544056.jpg?v=1784334273","url":"https:\/\/store.motormia.co\/products\/street-series-at-2-slip-on-muffler","provider":"MOTORMIA","version":"1.0","type":"link"}
