Finshed the exhaust last night. I bought the CX racing downpipe added a brace to it, so it would bolt to the trans cross member (I learned on my SR that if you don't hang your downpipe, you are going to be replacing exhaust gaskets constantly. The weight of the pipe pulls down on it just enough to loosen the bolts and the gasket gives out).
The downpipe ends about halfway down the transmission, so I decided I wanted to make the exhaust out of aluminum, bought the flange, piping and rod to make the hangers. The piping is .065" wall and 3" OD. The reviews are extremely mixed, I wouldn't try this if it was a street car, but I am very intrigued. My main concern is cracks over time, so I will just have to keep my eye on it.
I am happy with how close it sits to the car, since clearance is very important, I need to do more research on welding aluminum, the start/stop makes it very difficult to lay down consistent beads, but the welds won't break, that's for sure.
and I apologize the pictures are out of focus and dark
