View Full Version : another manifold question

08-05-2009, 10:31 PM
I have obtained a stock manifold for a shovel. I'm going to run it with a Super E. I know the throat diameters are not the same. I'm going to smooth the lip of the manifold up. Has anyone done this and have you seen a huge drop in performance? Thanks

A friend did that on a 900cc Ironhead and didn't have too much trouble, you should be ok.

Why not just get the S&S manifold? I doubt the stock manifold will flow as well.
