Quiet muffler

I currently run stock exhaust manifolds, added an X pipe last install. Last set of mufflers were Walker “Quite Flow” or the “Sound FX” mufflers I can't remember and I'm trying to do a purchase history search with no success yet. I know the 1st set was stainless and 2nd aluminized.
Back in the 80's, same car, Meineke asked if I wanted turbo mufflers and I said no, put the quietest mufflers you have on it. You really only heard it when the 4 barrels were open.
I'm looking at these but need to confirm I didn't already buy them lol. My other set is packed away in storage (In original boxes) :BangHead:
