It’s pretty much on all of them these days. It’s not even ‘new’ - the Jaguar XJ6 (RWD) with the big inline six had a pre-cat next to the exhaust manifold way back in 1979. Increasingly tight emissions regs mean that this practice is common now and probably going to be across the board for everyone in not too much longer. The closer the cat is to the exhaust manifold, the hotter it is and the better it works.
Pretty much de rigeur now. The below link is a pic of the exhaust system from the newer 5.0L Mustangs - the cats are bolted directly to the exhaust manifolds on those.
Thanks for the info. I’d love to get back into the hobby again, but it’s just not in the cards. I should still keep up on the tech, though.
