Did my first oil change on this car today at 2600 miles and took some time to observe the stock headers and the cat/GPF on the facelift Mustang GT.
The headers were incredibly disappointing in their design. A huge choke in the tubing (I think our RHD cars have headers about 10mm in diameter thinner than the USA cars), but also the dramatic bends to clear the steering column seemed largely unnecessary. There was maybe 3 inches of clearance and you definitely don't need that much. I'm surprised these cars are only 15hp down from the US ones given the choked up headers.
Also had a look at the cats/GPF and they look like they get really freaking hot. I can't see these lasting more than 30,000 miles, but they could break down sooner and cause a blockage which would be bad for the cylinders on the side that fails.
This is a 2019 GT with 2600 miles.
