{"product_id":"at2-stainless-slip-on-muffler","title":"AT2 Stainless Slip-On Muffler","description":"The Yoshimura AT2 Stainless Slip-On Exhaust is engineered for the Kawasaki ZX-4RR, designed to complement its high-performance 400cc inline four-cylinder engine. This Street Series Works Finish slip-on is crafted to unleash the full potential of the powerplant, which operates at over 16,000 RPM.\n\nPerformance gains include a 3% increase in horsepower and a 4.3% increase in torque, with the goal of enhancing power delivery throughout the entire spectrum. Beyond performance, the AT2 muffler significantly reduces weight by 4.5 pounds compared to the stock exhaust system, contributing to improved agility and handling. The sound produced by this inline-four at high RPMs is described as a notable improvement, with the AT2 muffler featuring an iconic matte carbon fiber end cap and heat shield that enhance the bike's aesthetic lines.\n\nThis exhaust system is proudly designed and manufactured in Chino, California. It is intended to fit standard, factory-equipped motorcycles. Compatibility with non-standard OE or aftermarket accessories not originally delivered with the bike may not be assured. Furthermore, this product has been designed and tested for the U.S. marketplace only, and compatibility may vary in other regions.","brand":"Yoshimura","offers":[{"title":"Default Title","offer_id":52664155308344,"sku":"14720BP520","price":639.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687544035.jpg?v=1784334269","url":"https:\/\/store.motormia.co\/products\/at2-stainless-slip-on-muffler","provider":"MOTORMIA","version":"1.0","type":"link"}
