VF LS3 headers and cats on VX LS1

[Ginger Beer]

G,day peps

Has anyone "successfully" fitted VF LS3 HSV tri-y header and cats on a VX LS1

I've managed to get a very low km full header back exhaust system off one of the boys at work

This system, if it fits, would be a cheap and easy way for emissions compliance when I go for a engineering cert and emissions testing on a project I'm looking at, I've been told that the HSV cats will be enough to get me through emissions on a good 98 tune

I'm not worried about the efficiency or performance difference between the stock exhaust manifold and the short tri-y HSV or aftermarket headers, just the feasibility of this being a cheap option for compliance

The system is sitting in my shed at the moment and if it fits without to much trouble it doesn't hit the bin

I believe the LS1 and LS3 heads have the same fixture points and exhaust ports

If you've managed to fit this what additional mods were required

I'm not interested in opinions though....just if someone has actually achieved this

Cheers
