Cool, thanks. I'm planning on using flex headers and I have some mounts I bought from DA. The pipes are carbon fiber so I won't need to build an elaborate pipe tunnel. The CF deflects the head instead of absorbing it like aluminum. Apparently, you can almost grab them while the engine is running. Anyways, I just basically planned on putting something in behind where the pipes exit to deflect air out.

I'm building this plane at my parents house so it's going to be March before I can touch it again and then it will be mostly preparing sheeting for the foam. I'm also planning on ordering the pipes so I can see and think about preparations for installing them.
