I don't know about the HS but I wouldn't want to deal with place racing . They told me they would ship the next day and a week later when i didn't recieve I called them and they said it was back ordered and would be shipped in 2 days after a month in a half they told me they are waiting for it to be made. All that after telling me it would be shipped the next day. so I canceled and ordered a stillen CAI. Any one that screws aroud that much isn't worth dealing with to me. I'd rather pay more for the stillen.
