the setup just lets water vapor sit in there and will ruin just about any muffler that is not 100% stainless steel. flowmaster or not.

Are you referring to the dual in dual out setup I'm thinking about getting?
I'll probably get stainless steel anyways

just don't mount them upright like in the picture i was referring to unless absolutely needed. even with SS. may consider making drain holes if needed.

i have that and i have flowmaster 40s and it sounds great. im gonna dump it but yea id get it
I had the 50 series you are palnning on buying. I since changed to longtube headers and 3 inch piping to a y-pipe in to a 50 series delta flow out to a 3.5 inch tail pipe with a big 4.5 inch single tip out the back like stock. I really need to get pictures of all that...

I have the setup you're looking to get, (Flowmaster 50 2-in-2-out) and I'm changing it. Don't get me wrong, every time I turn it on it turns me on with it's awesome sound, but my first time out on the highway with it I thought to myself, "You're going to hate that drone someday." True story.
If I were you, don't go with Flowmaster, they all drone. They flow better than stock, but almost any other performance muffler flows better than Flowmaster. I had a true dual Flo-Pro setup with some cheap long-tubes on my old 81 K5 Jimmy, and with as loud as that was, it was quieter inside than my Yukon is at certain revs. In fact, on the highway, it was quiet, for a 30 year old beater with no carpet...
Go with Magnaflow or Flo-Pro, you'll be happier.
