    Default Axleback Bolts

    Hey guys. I have been running without an axleback for sometime. Well I just bought an axleback and it didnt come with bolts and I dont have the stock bolts. Does anyone know the stock size and length of the bolts to connect the axleback to the headers?

    Thanks

    M10x1.5 35mm long for the axle back to bolt the mufflers to the flange.

    As these age and see a lot of use, this will be a common issue.

    I like to use ant seize on certain fasteners/joints.
