Looks good except for the welds at the flange. The welds dont seem to be ground as smooth as they could be on the inside. Does this affect performance??
Filing the welds at the flange may look better, but may weaken the weld around the flange. It's common not to flie welds on bicycle frames for this reason.
Since I don't plan on driving my car until about mid-April, I probably won't install it until then. But I will definately post some numbers when I do. I will have my ARC intake by then as well.
Got my new header!
