I knew what you meant about how the midpipes are attached but don't actually meet up with a x pipe or similar. One thing I couldnt work out is how it looks like a normal VF system but there is a join in the midpipes which I couldn't find any evidence of from hurricane. Looks like 4 into 1》ss cats》two parralel pipes with resie》 pipe to muffler》then muffler with dual outlet.
$1300 shipped with no guarantee it'll fit, no diameters given and 40k odd kms. Probably not worth it. Struggling to get a HSV ute system to SA but will keep looking
