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
