{"product_id":"fusion-axle-back-exhaust-system-1","title":"Fusion Axle-Back Exhaust System","description":"The Billy Boat Fusion Axle-Back Exhaust System offers a unique bi-modal design for the C5 Corvette (1997-2004), allowing drivers to choose between two distinct sound profiles. Each muffler contains two passages: a smaller, quiet side with a chambered tube, and a louder, straight-through tube. A butterfly valve, controlled by an included vacuum kit with a manual switch, regulates the exhaust flow between these two modes. The loud setting delivers an aggressive tone similar to Billy Boat's \"Bullet\" system, while the closed position offers a sound slightly louder than their \"Route 66\" system.\n\nConstructed from premium T-304 stainless steel, this exhaust system is precision-built with TIG welds and finished with a satin brush on the main pipes and polished, double-walled tips (4\" round or 4.5\" oval). The system fits to a stock H-pipe and is proudly Made in the USA.\n\nInstallation difficulty is rated a 3 out of 5, suggesting mechanical experience is helpful but not strictly necessary for a successful DIY project, which could take approximately 20-60 minutes. Billy Boat backs this system with a lifetime warranty against rust, corrosion, or burn-through, and a 2-year warranty against defects in materials or workmanship.","brand":"Billy Boat Exhaust","offers":[{"title":"Default Title","offer_id":52687100707128,"sku":"BBE-FCOR-0155","price":2235.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662152919.webp?v=1784880353","url":"https:\/\/store.motormia.co\/products\/fusion-axle-back-exhaust-system-1","provider":"MOTORMIA","version":"1.0","type":"link"}
