^^^ Dude, that's your opinion, and it's fine. I do LOVE Mac exhausts though, and my friends have em to, but I will not go that route once I switch the Flows.
Personally, Mustangs sound the best with Flowmasters. I know, I know, everyone has em, and they all sound overrated. But, they have that perfect hollow sound that distinguishes it from other Domestics. Especially hear a carbed. 60's stang with flows and LTs.....OMG..... :drool:
