Just wanted to let everyone know these flanges are AWESOME!

David made me a set of -10 flanges for my S5 T2, and these things are a work of art. Highly recommended, especially if you need to re-route the plumbing for any reason or if you R&R your turbo often. In my case, I needed to re-route the stock return pipe to clear around the OMP, after installing the Rotary Aviation OMP adapter.
