I'm still going over this decision myself. I commute 55 miles daily, and almost all of that is in the drone rpm range of 1,800 or so. I have 3.31 gears unfortunately.

I looked at the underside of the Boss 302, and noticed they have small resonators on the rear mufflers. I wonder if I have 12" resonators installed if that would prevent the droning?

I'll probably have the flows installed first and see how it goes, then add resonators if they bother me.

FiveOh motor sounds better with an X, 4.6 sounds better with an H.

Add 3.73's. Problem solved. I barely noticed a change in MPG's. It's there, but not much at all. I drive mostly highway myself. If I cruise at 70, which is not often, I'm slightly below at about 2100-2200 RPM. And let's face it, you already bought a V8, so you knew going in you're not really after fuel economy, LOL.

Like it says all over this forum... "Don't fear the gear"

I gonna tell you from experience with my v6 which I know is different from the V8 but I honestly wouldnt get them again. The sound great for a 6er but they drone like nobodys business. I would look into something else if I were you.

....not a problem at all with a manual tranny, I have them on my car and they only drone around 1900/min and the sound is awesome.
