Yes, in both power gains and sound.

In my (and most people's) opinion, no, it's not very loud. Especially when using headers with the 'high flow catted' X-pipe.

No, the cutouts (with stock manifolds) would usually have a much louder sound than headers/stock mufflers with no cutouts.

Do you mean in the actual header collectors themselves...or just using headers along with cutouts like how you have them now, further towards the back of the car?
You can use cutouts along with headers but it can get very loud.

On my car, LTs with catted-x did not add as much volume as the over-axle did.....of course, I did the over-axle first, so it's not a 1-for-1 comparison.
