Review on πŸš€ Improve Performance with ATP Automotive Graywerks 101140 Exhaust Manifold by Christopher Bates

Revainrating 4 out of 5

Everything matched. Inner Casting

I bought this to replace the original warped header on a 194. All bolt holes line up and the valve stem works well. Everything went well together. However, the inside of the casting is terribly rough. I'm sure the flow properties are terrible. At least it's easy to install and work, which isn't always the case with repops.
