The turboXS also has the CAT at a lower position but the bellmouth transition is quite generous and I don't believe the stock shield would fit without some modification. I did attempt to fit but be honest I only had a quick test because I had decided I didn't want to cut it at all. If you look at these photos you will get the picture.
I just think the DIY heatshield is worth sharing with others who either don't have their original or want to maintain it untouched. I did too many small mods on my old wagon that turned into big mods so it would be impossible to ever put it back the same as how I bought it. I decided when I bought this car to make no mods I couldn't easily undo. Personal choice

Shav I don't know mate. I am not sure what is different with the auto fitment but if it is just the angle of the pipe to allow for the wider transmission my linked photos may help.
