Not sure about diameter but I know the angles/bends change slightly. It can still work but be aware before buying you will have some possible issues depending how big your spare parts bin is. I forget how exactly I got mine to work, been a long time but i have a few various exhausts bits laying around.

You can use the Stock SP2 header on a SP1 there by opening up many more options for the slip ons.

Where the mids clamp on the the header, no difference in size. However, there is a difference in the angle of the midpipes as mentioned above. SP2 midpipes won't work on SP1 header. Unless you can cut and weld. Or replace the header with a SP2 header.
