Anyone use Magnaflow mufflers? What do you think?

Well the "Fagnaflows" are installed, I'll post a clip tomorrow (but don't quote me on that".
One thing I'll tell you... These things are LOUD! maybe these are 1979 Magnaflows or something? It's not why I expected that's for sure.
Wheither loud means good I don't know? I'll post a clip and you can give me your opinions.
Thanks.
