My SPS manifold cracked too -
Now to be perfectly honest it probably cracked because the brace on my decat wasn't attached to anything. Dane's customer service was top notch and he offered to have it repaired for me or have a large chunk off one of his hybrid manifolds. You can't ask for much more than that. Absolute top notch trader he was.
On the other side of the coin, I bought a Zisco manifold. Although it looked awesome there was a bit of splatter on some of the runners from the welds. Not as neat as other Zisco Mani's I have seen, no big deal though. I fitted the manifold and the second runner fouled the IC hot pipe, it fouled it so much I had to grind away a reasonable amount on the pipe flange. It also pushed the pipework into the rad. It was a very VERY tight fit.
Regardless how good a product 'usually' is, there are always going to be a few which are below the norm quality. It's basic statistics. The more that are produced and sold, the more chance there is that a few are defective. That's the joys of buying handmade items.
what intercooler do have, and was the mani made with these in mind? as i know he makes ones to suit top mount, ones to suit top mount and efi pipe, but doesnt make one that will fit the autobahn style ones
