I use their manifold, its basically the same design you will find all over ebay. I wouldn't buy from ssautochrome/xspower, because they do not stand by their warranty, and if they send you the wrong part, they will not answer your emails. Buy off ebay, and you will have paypal back you up on any warranty that is offered.
I have bought several items from ssautochrome/xspower but will no longer do business with them. Just recently, I ordered a 4-2-1 header for a Honda Civic from them, and I was sent a 4-1 header. They do not have a phone # for contact, and all email and faxes go unanswered. I made a paypal dispute, which they refused to help stating they cannot verify description of the item purchase. So I was stuck with an item that was basically worthless.
I found this webpage when i was searching for a contact #
