Nice build, way nicer than my grocery getter will be.
I do have another question. I ask out of ignorance b/c I really don't know.
*Why are the waste gates routed back several feet to tie in to the exhaust behind the firewall instead of dumping into the down pipe right after the turbo. It looks like it would cut out some tubing.
Again, really nice job... Everything looks well thought out.

No worries on facebook / IG messages, I check those more regularly.
I asked the same question to the turbo fabricator out of my own curiosity. He said there is a minimum distance you want the wastegate dump to recirculate into the system to avoid getting too much turbulence on the backside of the turbine housing. He said typically he does 12-18" away. If you look at the distance of mine, it's about 20" and that's about as clean as he could make it with the space constraints.
It was an option initially to have the wastegates dump to atmosphere but I was worried with the boost i plan on running and the size of the turbos that the gates will be open pretty regularly, and was worried the additional noise would be annoying.
