Exhaust or not

[larbec7]

I have an 2006 GT 4.6. I just took the stock mufflers off and replaced them with some Flow Masters 40. If I take the Flow Masters off I have a few questions.

1. Will I notice a substancial difference in loudness?
2. Will I have to do anything to my electonics to prevent getting any airflow sensor error codes or any other codes
3. Will I have to reprogram anything
4. Will I get bad popping noise
5. Will it sound like crap or will it sound good

Thanks

Probably a good question to ask the S-197 forums; http://forums.stangnet.com/forumdisplay.php?f=84
But if you are talking straight pipes my guess is that it wont sound too good, will be louder, probably no further gains or little, will likely get a popping noise due to back pressure, but wont need to change any electronics.
