I wanted to do this over a year ago and just never got around to it. I had ordered the fog bulbs (H7) a long time ago when I upgrade my headlights to the 55w DDM Slim Ballast kit but found out the hard way my stock HID ballast would not work with the bulbs that I had ordered. So I order the Apexcone Raptor HID Kit from DDMTuning, which are about twice the width of the Slim ballast kit. I wish I had gotten the Slim Ballast kit because finding a area to put the ballast and not block air flow to the intercooler was not easy. I finally settled on placing them under the intercooler ducting and the inside lower part of the bumper. Kind of hard to explain. Either way they are out of sight and should stay pretty dry. The fog lamp housing requires a little modifications to get the HID bulb and wiring to working. I'll try to post some pictures to show you what I did. After some quick wiring I got everything fired up. I was surprised to find out that the beam pattern is pretty sharp for the fog lamps. Almost comparable to a projected headlamp (meaning: using optical lens). I re-adjusted the fog lamps levels to make sure they were not pointed to high. With 55w HID headlamps (compared to stock 35w kit) and 35w HID fogs, the last thing I want to do is blind people and or get pulled over by the local authorities. So they have a 10-15 degrees downward angle similar to the headlamps.
I took it for a test drive and living around Seattle, WA it was raining hard. The conditions were perfect since 3000K is a true yellow color so it helps illuminate the road better then other color ranges in wet or foggy conditions. At first, I was a little disappointed that they weren't brighter but then realized that this ballast kit aren't as quick to warm up vs. my the Slim Ballast kit. I would say they take 30-45 seconds vs the 5-10 seconds for my headlamps. The color starts off as a warm white color and then gradually turns to a true rally car like yellow. Once they are fully warmed up they work perfectly with the headlamps. The 4500k kit in the headlight is great at distance while the 3000k in the fog really brings out the road 20-30 feet from the front of the car.
In summary, I'm really happy with the overall setup. If you live in a wet or foggy area I would highly recommend this setup. I hope to have pictures up in the next week. If you have any questions feel free to post a comment below.

I'm sorry this took so long to get up. I know a lot of you have been asking for this video and I wanted to make sure it wasn't crap. I also wanted to make sure the exhaust was fully broken in. I do have to say that Audi did a great job keeping engine and exhaust noise out of the cabin because it wasn't until I make this video did I really notice what this exhaust system sounded like. I how you guys in enjoy the video!
