The deadline from the vendor was six weeks after receiving the product. I received the product on 3/1. I'll have my writeup done by the deadline, sooner if I can find the time. As much as I love hearing my new intake and exhaust, the road/tire noise gets a little old on my 60 mile roundtrip daily commute (especially since I switched back to my 255/295 summer tires a week or so ago). I'm looking forward to doing this install and posting the results.
One thing I'll mention in advance of my install/review is that I had an issue with how much my credit card was charged (shipping was not included in the giveaway and I bought a few extras to facilitate the install). A simple email to ANT from Second Skin was all it took to resolve the issue. GREAT customer service so far.
