That's the shop's fault, 100%. Any time you buy a tubular manifold, there will be slag inside it, unless it's welded by professionals, and backpurged. When Boost Designs was sponsor of two forums, and everyone liked them, I bought a manifold to replace my revhard. And after spending $450 on the manifold, I spent 3 hours with a dremel and chisel getting slag out of the manifold. That's just something that the shop should have known to look for. However, my BD manifold has 4 welds per runner. The SSA has 2. What do you think has/had more slag in it? And I'm 100% sure that without deburring my manifold, I'd have a brand new blown Precision SC50.-Jeff
A rule of thumb for me is not to trust someone else's work. At least not 100%. Inspect everything before using it. When I had replaced my Revhard mani, I inspected the new one and found a small rod lodged inside a runner. It looked like somehow it got casted into place. It was rather easy to remove but could have caused a catastrophic turbo failure had it come loose during operation.
