HI there, I'm due to get my first Mkiv supra RZ twin-turbo next week! I've seen lots of good info on this forum about them so i've decided to join!
I've been reading the BPU section and im very keen on doing it to my supra. I have a few questions though, regardging the replacement of the cats, am i right in thinking that theres a cat in the back box of exhausts? alwell as the one next to the mainfold that get replaced with the d-cat pipe. If my supra already has a full s/s exhaust system, how do i tell if its a de-cat system? and finaly, where can i get a "restrictor ring"?
Cheers.
