Xj40 stock exhaust

Hope everyone is doing well, I’m looking at adding a x pipe for my 1993 xj40 for a bit of growl. What is the factory piping dimensions and does anyone have any x pipe tips?

Have you looked at the exhaust system on your car? My understanding is that a X pipe works for a V8 not a i6
This should be representative of your system and as you can see the exhaust joins after the down pipe and then separates out again.

Actually I have not yet, I must of been misinformed because I was told that x pipes were a simple bolt on on xj40s.
