If anyone could give me a FIRSTHAND account of their experience with a company called Sparktec Motorsports. I have seen both sides of the issue with equal frequency:
"Got my LSD in a week",
"Didnt hear back from them for a month, finally got my money back from paypal"

I just bought an OBX header from them and was wondering what to expect. Haha, i know, a little late right?

Thanks in advance for any input.
