I have a XS turbo and 2 manifolds in my shop. I have to say the quality looks good, but I haven't put them to use yet.

Im using an XS single turbo manifold on my RB26 build up. It cost me $200 were as a HKS one can run for as much as $2000. When doing research on it I found that the early designs for RB's cracked a lot, but supposedly the newer design doesn't. It was also recomended to brace the manifold to help support the weight of bigger turbos.

Like you, I figured for $200 I could justify having cracks fixed or even buying another. Especially when the the cheapest "high quality" single turbo manifold I have found in the past year was $800 used.
