hi all,

I'm planning to replace my muffler this this weekend on my 90 carat. got all
the parts muffler,gaskets etc. Just one question, between the side exhaust
elbow & side connector pipe there's an exhaust donut (metal ring), is there
suppose to be some kinda sealant or just a metal to metal application? the
reason I ask is the way I look at it, I'll have to remove it from that point
to remove the muffler and replace all the (3) gaskets. Just want to make
sure I got all the parts needed to put the new muffler back.

Thanks,
ruben......
