Lots of hills here in VT, so that range is hit often. The drone got so bad that it was giving me a headache. Weird thing is some passengers said it wasn't that bad. As I learn more about exhaust drone, I am finding that it is more of a 'feeling' than a 'sound' and affects people differently.
The startup sounds and growl at everywhere else in the rpm range was excellent, but just wasn't worth the drone at 2k. I like to cruise in this car and started to not enjoy rides. I ended up putting the stock exhaust back on and enjoy the car again. Problem is, since I removed the stock sound tube because of installing an Airaid MIT, the car is really quiet now.
I figure I would save up for a Borla since they claim 'zero drone'. However, learning from these posts, it seems that Flowmaster or MBRP may work.

I looked at that NXT axle back as well. Price and quality looked outstanding, but the size and shape of those mufflers is what turned me away. And your experience basically backs up what I suspected. When you consider the V6 naturally has a higher pitched and more raspy type note just based on design, then it seems obvious that aftermarket setups need to be chosen wisely.
I ran that Airaid MIT for a while as well, but I could barely tell a difference in sound. Maybe very slight, but very little. Since then I went with a AEM Momentum GT CAI, and hooked the sound tube back up. That made a pretty big difference in sound
