the 4.6 sounds wicked with dual Magnaflow 18" Bullet mufflers
I had the Magnaflow Magnapacks on my Mustang GT with 4.6 2v....pure muscle sounds
kinda loud though, but damn if it didn't sound awesome.

I have an 06 with a 4.6L I put the flowmaster american thunder catback system with a forty series single in dual out and it sounds great. It also picked up my hp a little bit and got me an ext mile to the gallon. It was really easy to install, only took about an hour and a half.
