{"product_id":"bi-modal-exhaust-system-1","title":"Bi-Modal Exhaust System","description":"The Billy Boat FCOR-0561 Fusion exhaust system is a bi-modal, axle-back system engineered for the 2006-2013 Chevrolet Corvette C6 Z06 and ZR1 models. This system offers two distinct sound profiles: a quieter, muffled and chambered tube for everyday driving, and a louder, 3-inch straight-through tube for aggressive acceleration. The bi-modal function is managed by a vacuum valve developed by BBE Performance Exhaust, which operates based on RPM and throttle input, providing a controllable exhaust note that ranges from a deep, aggressive tone to a volume that will turn heads.\n\nConstructed from premium stainless steel, this exhaust system features TIG welding and a satin brushed finish with polished 4.5-inch double-walled oval tips for a spectacular look. The Gen 3 systems are specifically designed to offer a greater range between the quiet and loud modes, making them ideal for Corvettes with additional modifications like headers or engine packages. The system is a direct replacement for stock components and includes all necessary hardware and gaskets for installation. Billy Boat backs this system with a lifetime warranty against rust, corrosion, or burn-through, and a two-year warranty against defects in materials or workmanship. This product is proudly Made in the USA.\n\nFor Corvettes without the factory NPP (performance exhaust option), Billy Boat offers a separate Fusion retro control kit (Zip # EX-2217) to enable bi-modal functionality. This kit is not required for Corvettes already equipped with the factory NPP option. The FCOR-0561 system can also be paired with an optional BBE Performance X-pipe (Zip # EX-2107) for enhanced exhaust flow.","brand":"B\u0026B","offers":[{"title":"Default Title","offer_id":52687098872120,"sku":"FCOR-0561","price":2571.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662152899.webp?v=1784880330","url":"https:\/\/store.motormia.co\/products\/bi-modal-exhaust-system-1","provider":"MOTORMIA","version":"1.0","type":"link"}
