I did read somewhere It should fit,
because I have L67, and I was after a replacement exhaust, and search various options,
but an exhaust guy said that he would make one up, [Don't think that was the option I was looking for and going to happen] !
So I passed on that idea,
I searched on eBay, and there were few that indicated the same exhaust would fit a L67 and S1 Vy SS,
With that being said, they could different mounting points, but one would assume the under body would all be the same, as they used the same Floor Pan for the Sedans.
