This picture makes your outlet pipe look VERY close to the exhaust manifold.
On the speedtech exhaust manifold those flat circle with the hole in them Is it tapped or could you tap it? Might be a easy way to mount a heat shield.
I noticed you said you have no E85 available. You should really think about running meth then if all you have available is 92 octane.
You can reroute your windshield washer tank fill neck I believe, at least you can on E90/92s. Might give you a bit more space as it looks like your outlet pipe is going to be touching and or rubbing on the heatshield for the washer fill neck. You could always pull the silicone pipe away from the exhaust manifold as well, constant tension.
Glad to see your project is getting closer to completion!
