Hi,
Just a tip about the cat. Most motorbike exhausts have an integrated cat nowadays, including the nice aftermarket ones (carbon, stainless steel, etc.). It can avoid the need of fitting either an ugly cat on your exhaust line, or a very expensive better looking one

.
I needed a cat with my Sierra DOHC, and I fitted a BMW K1300R exhaust a friend gave me. I'm still not sure about the emission test, but as it has to do with the year of the car, it should pass. No way to know about it beforehand anyway
