Have you or one of your customers installed GMS 500 turbos with the GMS cast manifolds? What were the results? Your website information on the cast manifolds is somewhat nebulous and I think your manifolds could be a price competitive option to the GD manifolds. I have searched on many separate occasions for information on these manifolds and found nothing. I emailed you once about it, but my tentative nature probably steered you away from me and toward your more definite customers. I understand. Before anyone posts "Why don't you call Chip?" I must tell you that I am a cheap bastard when it comes to long distance. Thank you.
