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.
- Manufactured from bronze to withstand high exhaust temperatures
- Includes center adapter stud to pinch the baffle in place
- Fitting required
- Use on 1936-1953 24-stud engines only
