The Rt.66 exhaust system is the modest system offered by Billy Boat Performance Exhaust for the C5 Corvette. While the main focus of the Rt.66 is cosmetics, this system does offer a subtle change to the exhaust note. Through a combination of sound absorption and cancellation the RT.66 mufflers emit a nice mellow touring sound slightly louder than the OE system throughout the rpm’s.
The 2.5” CNC mandrel bent tubing along with straight through design mufflers provide for a smooth uninterrupted exhaust flow for increases of as much as 11hp and 9ft.lbs of torque over stock. Quad 4.5” elliptical tips give the car a bold yet distinctive look. No emission components are altered with this system therefore it is 50 state emissions legal and is backed by a limited LIFETIME warranty.
