Hi Chuck,

I also have the Hall headers and muffler combo and have fought for years
with the donut gaskets squeezing out and causing exhaust leaks. Last year
while at a local muffler shop known for great work, the owner heard my tale
of woe and created two short tubes to keep the donut centered. He cut two
short lengths of tube with an OD to fit in the donut, and then used his
machine to adjust the diameter of half the length of tube so it would slide
into the pipe that goes from the header flange to muffler. Once inserted
into the pipe, the donut goes on and the assemble is bolted to the header
with the original Hall flange hardware.
I have been running this setup for the past year and the donuts stay in
place. I have attached four photos showing the small tube and application.
Although it reduces the header flange cross section a bit, the tradeoff of
not having constant exhaust leaks at the donut is worth the price of
admission to me.
