I have had it for about 2 months and absolutely love it. I still think it is the best bang for your buck. I paid 350 shipped. If you search you can find the group buy thread where i bought it from. You will not be dissapointed.
I just put the magnaflow on as well. It is great, not loud when cruising around neighbor hood, but sounds great when open it up. It has a nice low rumble when you start it up as well. I paid about 300 at a site called performancecenter.com
I have a magnaflow cat-back system and i love it!!! it sounds great and i can feel the small difference...but thats probebly just a misconception cause its so damn loud it feels faster...LOL
