Magnaflows = good choice for not loud and HP

I have magnaflows welded in to the stock exhaust and I have 'zero' drone...
Yeah, I had that exactly. Everything stock except for the mufflers, which were regular Magnaflow. I changed to a MAC because I couldn't hear the exhaust as much as I wanted, plus I decided the mandrel bending couldn't hurt.
The MAC sounds great, but it's a totally different sound than the Magnaflow. To be honest, the Magna's have a great 'purr' sound that is hard to beat. I considered Magnapacks, and probably SHOULD have gotten them, but I still love the way the MAC sounds. It's more growly, and definitely deeper. I don't know, I'm probably equally as happy with the MAC as I would've been Magnapacks.
It's going to be plenty loud soon enough, because I'm going to add a high-flow catted X pipe.
Magnaflows won't be loud. Magnapacks, I don't know. Probably WILL be loud from cars I have heard. If I'm not mistaken, Magnaflow actually tends to give the most HP increase. You NEED to read this link:

That was very helpful to me! I believe it was Bassani that gained basically nothing over stock as far as HP went. But, they said that with a tune, it would've done really well. Seems like Magnaflow is better setup for a more stock 'stang.
