Can one leave the exhaust pipe connected, and still have enough "play" to get the manifolds removed from the engine and the new gaskets in place?
Probably a dumb question, and hints at my impatience/laziness...but the flange seems seized up pretty good. And I'm not really wanting to destroy it just yet.
Breaking flange bolts is not recommended I have chosen to use a sawzall an cut the tail pipe, replace the gaskets resurface the manifolds,or whatever then weld the exhaust pipe back together or take it to the muffler shop and pay them to do it.
