Howdy,
Quick question, I am going to oversize the 3" exhaust ports in my transom to 4", going to lightning headers from stock Harman logs.
Should I glass in the interior of the through holes then install the tips or just install the tips with gaskets and silicone?
Obviously intending to use a gasket and silicone to seal the tips either way.
Thanks!
Josh
