seems a very good price.
if your going decat route they going to chop off cat and weld onto exit manifold like ktec or you having a new one put in?
stick with 4-1 if you going that route
not sure mate,got to make that decision this week on whether to have a new manifold,price goes up if thats the case to well over 4 figs,but if your going to do it, you might aswell do it right the first time rather than going back to it another time.I will keep you all informed.
