Exhaust packing.

Attachments :
    Ive a 1925 Seven seat sedan. Did you manage to unscrew the flange nut? I didnt want to run the risk of breaking mine so I wrapped it with titanium tape secured with stainless steel cable ties and it seems to have done the job of sealing any leaks and it also insulates.

    I started the wrap on the manifold just above the flange and carried it down the pipe about 12 inches.
