To get the most power possible out of a C6 Z06 header requires a long tube design. Billy Boat of B&B has designed a long tube, stainless steel header set that will provide you with both horsepower and torque throughout the entire RPM range, the result being a much faster Corvette! B&B headers are 1.875" diameter tubes that flow seamlessly into a 3, 4 - into 1 collector. The headers include installation hardware, 3'' X- Pipe and gaskets and are backed by a manufacturers limited lifetime warranty against rust, corrosion or burn through. For Off Road Use Only.
