4.7 gibson exhaust
does anyone have the gibson cat back system? I currently have just an afe intake and was wondering how others mileage looked with this type of set up, if anyone has any better thoughts of an exhaust please let me know!

From what I read, the Gibson is best on the 5.7. Magnflow is the way to go with the 4.7.
