Finally got my Milltek installed last night on my 01 A4 TQM Sport. The quality is exceptional. The welds are great, piping fit together (only needed very minor massaging), and it looks great. My only complaint is how loud it is, keep in mind that I purchased the non-resonated model. I highly recommend getting the resonated version to anyone looking at their systems. I'm probably going to get the mufflered center section and am very curious how much quieter things will be. Other than the noise, I'm very happy with the quality, install, and looks of the system.

 

any exhaust system without a resonater will be freaking loud, mine is still kind of loud even with one

 

Yup, that about sums it up. I was told that their resonated version was roughly the same as stock and that the non-resonated would give some additional exhaust "rumble". LOL

I'll tell ya this tho, my K04/GIAC combo loves the freedom to breathe!
