Since I am probably the only one who has lived with both a Milltek and an AWE system long term I would say based on your criteria go Milltek. Nothing against AWE but it IS louder than Milltek. Both produce similar HP numbers, AWE's is lighter and shinier, but Milltek has the least amount of extra noise in the 2400-2800 rpm range where the Tubi and B&B can be on the atrocious side and 9ff flat out flatulent.
If you want something that sounds agressive only when you get into it, but otherwise is civil around town then Milltek is the way to go. If you want something more agressive more often then go AWE or
Fabspeed. Remember volume isn't everything, but TONE plays a significant role and that's where hearing the exhausts and LIVING with them makes a big difference. I know people who get all excited about their new LOUD exhaust because they just shelled out $$$ for it, a few months later it becomes irritating to them or they can't take the "drone".
I also found it interesting to go back to stock for a day between the Milltek and AWE systems as I had grown accustomed to the growl of the Milltek that was no longer there in the stock system but came back in force and then some with the AWE package.
With regard to installing the systems I think AWE is easier than Milltek but Milltek is a close second, everything else takes longer to install and in some cases requires "straps" to go around the mufflers (example B&B) which I personally don't care for but that's a personal choice.
Best of luck and let me know if you need anything more! BTW, did you notice the Milltek catback for sale in the
Classifieds?
