LS3/6L80e Engine Swap into my 73

Great update! Thanks for following through.
So regarding the mufflers… What exactly did you end up with?
And just for the record, what magna flow model did you have? I guess basically the inlet and outlet size, is it a dual or a single inlet/outlet, and what’s the overall size?
Thanks!

I originally purchased the Duff SS dual exhaust. Here is the muffler that’s included in that kit.

It’s a straight through design, meaning no restrictions. You could look through one end through to the other.

I went with a fully welded Street Performance ECO Plus muffler that‘s the same size.

Sounds like the ghost of Henry Ford almost got you! Better safety lock that oil filter on there now. Just sayin
