I changed the collector/reducer from a ball style to a flange end. The flange style definitely seals better even though the stock headers have some sort of ball end. I installed the muffler turnouts and the exhaust tips. The tips are not welded yet as I need to trim the length. I keep wondering how many more times I’ll need to remove the exhaust assembly—at least one more time to finish welding a few spots, spray the exhaust with hi temp paint and wrap the tubes using DEI Titanium header wrap.
