catalyc converter...

here's another image of the S3 XJ6 y pipe

here's the drawing of the Y pipe for the Series 3 XJ

sorry, the image won't load, too big. I'll reduce it and come back later
with a smaller one.

I uploaded image of the European Y pipe with Part numbers.

Some XJ cars pass without the Second, Y pipe catalytic, some don't, it depends on the emission limits in VA. Mine passed without any cats or dogs or any restrictions in the exhaust.

Note: the Company Double S in Canada sells a 3-piece Y pipe. Don't bother with it, it's only made in 3 pieces for their convenience and their arrogant attitude towards the USA makes it a worse deal, well, you do the math.

I got mine here in the USA and didn't have to deal with stiff upper lips
if you know what I mean.
