Back in the saddle, I've built the riser and insulated it and started cobbing the exhaust. Cletus Pew is right, our red clay is perfect for cob. I had to back off on the amount of sand I added because it was getting to stiff to use by hand, my recipe (which is totally scientific) is one 4 cuft wheelbarrow full of red clay, 25 lbs of sand, 8-10 big handfulls of cut straw and add water to taste...err...feel. I spent a lot of time worrying about my manifold and used rocks to create a nice dry stack of how i wanted it to look, a ton of building and tearing back and generally wasted a lot of time. If I had realized cob was as awesome as it is I wouldn't have even considered a stone for that area.
Anyone that reads this is is intimidated by the manifold area, here is a word of advice: just use cob! Don't over think it! KISS (Keep It Simple, Stupid!)
Anyways, hopefully I can get some pictures tonight, its hard to take pictures with red mud up to your elbows!
Thanks for the support guys, I'm glad to be a part of a group like you!
