Details

A Speedway Motors exclusive! The center exhaust ports on flatheads are siamesed. Our baffles separate these two exhaust ports and prevent reversion while decreasing the dilution of the intake charge. These are a must for high-performance flatheads. The baffle is held in place with an extended stud that replaces the stock cylinder head stud.
