Heard a few ppl say that the scorpion is a restirctive zorst on a 2wd cossie!

whats restrictive about it!?

As I have kept the down pipe back box off my system as the middle was fooked!

I was gunna use the down pipe & back box on next project & then get a local zorst company to make up a straight through centre section!

Guess what i am askin is was it the centre section/box that made the scorpion restrictive or was it the back box or just the hole system!?
