I'll quote:The turbo support brace is needed with this manifold because it built from .049 and .065 tubing. The support brace is made from .065 chromoly tubing. This entire setup weighs only 8lbs which is a lot less than just a basic manifold built from schedule 10 pipe. The tubing and merge collector is 316 stainless steel and the flanges are 304 stainless.
