Figured out why my Duster was so slow

View attachment 1715719140 Here’s what my exhaust manifolds look like. I had a leak on the driver’s side because I hadn’t got a flange on quite flat. So I buzzed in a little 6011 and milled it flat.
A trashed connecting rod makes a nice collar for bolting the exhaust to the manifold.

I like them, really cool to see that an engine swap can be done without buying everything from the shelf.
