A little criticism...and I guess I should've posted on here sooner, like before you got the exhaust done

You should've went with your original plan. We're talking about enlarging the pipe diameter by 1/4 inch, from the stock 2" to 2.25" that you have. That's nothing. Yes it'll be better than the stock piping, but it would've been even better going with at least 2.5". And for better flow, the straight through Magnaflow muffler would've been better than the baffled Flowmaster, but if all you're after is the sound, then it doesn't matter.

What was a good idea was getting rid of the stock resonator. I don't know if you looked inside of it when they took it off, but it's incredibly restrictive.

"2.25" Non Boost
2.5-3.0 - Moderate Boost
3.0 - omgwtfbbq Boost"

This isn't a small displacement 4 cylinder we're talking about. What you posted would be accurate for a 4 cylinder around 1.6-2.0L. Any larger engine and you'd want larger diameter pipe. I don't know why everyone's so afraid of getting larger piping. It really will help the exhaust flow better and you can still maintain velocity for the low end.

3.4L out of a V6 is a decent amount of displacement and something more like this would be better:

2.5" - N/A, few bolt ons
2.5-2.75" - N/A, many bolt ons
3" - N/A, many bolt ons, port+polish, cams, high compression
3" or more - Any amount of boost

It's a baffled muffler, metal plates direct the exhaust in different directions. There's nothing to break in. It does sound good though
