Just an update after a weekend of driving. Like I said before the exhaust sounds good under WOT. However, it doesn't sound so good when just driving around normally. It's forced me to drive the car in manual mode (which is pretty fun, but not like have a stick). The transmission likes to go into 6th gear pretty early and the tone of the exhaust around 1250RPM is blah. Staying in manual mode keeps it more in the 1500+ RPM range and it sounds good for a V6.
I will say that is exhaust is very nicely made. You can tell it's using good quality materials. Not sure how much time when into the exhaust sound tuning though.
