OK Im back, Got busy with the cutter and it basically fits within 2-3 inches, I will have short tubes welded on the original head flange and chop the intake is I can try the shortest possible AND the longer possible very easily, I build a loop big enough to double the length. I will use silicone couplers like the SHO manifold pictured I will ALSO be able to make the 3" version rather simply, DBW FTW!

So in the end I can only ask this, If I double the length, what happens to your 1/4 mile ET, MPH, 60 ft? What happens to 65mph cruising and passing power? This car did surprisingly well at 90mph when it was stock, gotta love the aero.

I do have a second Insight as well, it will be a D15 turbo (GT2554r) CNG and Flexfuel bi-fuel system, tri-fuel if you will and 200hp, will be geared really tall as well. I will do that build thread here.
