Yes, it is not.

Yes (sorry no pix, didn't bother removing the one I had here for a

Good question. Either way, to take full advantage of the upgrade you
will have to rebuild the entire exhaust system.
I suspect the 4kq is better - but if you already have the 87.5 bits or
they are real cheap... I'd still use the 4kq stuff. It is a *lot* of
work to swap the EM on these cars - it's not fun even if all the nuts
come off nicely like 3 year old stainless - it must be a terror on a 14
year old car with the head still on. So you might as well get as much
as you can for your efforts.
