Exhaust Star Nut 38mm
This is a high quality replacement star nut for the exhaust headers. This would technically fit all models /5 and onward with 38mm headers but it is correct on 1977 and later models.
Note: This will not fit R45 and R65 models! If you have one of those, please click on the Related Product.
Don't forget to put some anti-seize on the threads! Our copper paste is an excellent choice. (Link under the Related Products)
