Hi, did anyone on here build or had somebody build an moore exotic header arrangement...with Busa engine in the VortX ?

I got the MNR supplied SS 4-1 and thats ok, but rather heavy and compared to the more exotic bike aftermarket headers really heavy and also different in pipe sizes.

As i sit on L-side any additional weight loss is extra valuable.

I took mine to AAS in Newcastle.
Much bigger headers and custom built, improved the torque down low a lot, lets it run out of screaming revs at the top end.
Wrong side of the water for yourself but what are your options?
