Hi Joe,

I was hoping that it was the opposite - shortening would drop the RPMs because if it comes on the pipe at 31mph headwinds of any strength would make the thing useless unless I get a longer manifold built.

There is not a single company in my town who can or will help me adjust the shape or length of the manifold - even 'engineering firms' cant or wont. Is it me or are are people getting less helpful as the years go on?

I did think about drilling and tapped screws but there is very little room to do that and I dont want to block things up any...

I'll think of something..
