flowmaster muffler swap?
flowmaster muffler swap? if a car has the 80 series flowmaster for the lt1, would they be able to cut the 80 serioues muffler out and fit a flowmaster 40 or a super 44 instead? if its not a direct fit what would have to be done to make it fit?

You mean the inlet pipe is too thin? I don't know of any flanges on flowmaster mufflers. FWIW, I have had a single in/out muffler clamped, not welded, in the stock location without the driver's side tail pipe hanger for a few thousand miles now and it's still rock solid. I had to remove the muffler yesterday and it was pure hell trying to get it to let go of the intermediate pipe.

Here's something that I don't quite understand, An 80 series Flowmaster is built just like a 40 series on the inside except for the fact that it's partitioned off for the exit area. It flows strait though and when it gets to the exiting end it flows to the partitioned side and exits out the tailpipes. To me, saying that a 80 series doesn't flow well is like saying that no Flowmaster flows well maybe that's what people are saying and I'm missing something. Here's a pic of what it looks like inside
and here is a super 40 since there isn't a regular 40 to show 
See how similar, if one sucks it only makes sense to me that they all do
