AWE vs. Milltek vs. APR
#2
I'd have to say go AWE based on the extremely high quality construction.
I also like the amount of information that they provide. In the link below you'll find dyno results, dB measurements, pics and even a video clip. I especially like how they use flanges instead of slip joints.

A4xIV just had the AWE installed w/ Ecode Test pipe. It sounds pretty damn good.
The ONLY thing I didn't like was the fitiment of the exhaust. The left pipe hangs lower then the right side.
