Did some GTi-R manifold cleanup
The ports looked *really* small on my GTi-R manifold and didn't match my gasket. I decided to do some port matching and clean it up a little and that snowballed to over 5 hours of work on it. I was able to reach about 60% of the inside of the manifold and they came out pretty damn good for my first time doing anything like this. The pics don't do justice to how smooth it is. My turbine housing was extrude honed and I'd say this is approaching 75% as smooth as that.
