Hey guys, I know this is a done topic but im searching for an answer from people who have done this, anyway, I'm in WA with an r32gtr, took it over the pits and have to get it engineered, which means a 5 gas test.
I went over with cams and failed hard, so am going back to stock for for the test and some id1000 injectors and tune to suit.
Where I am struggling for a definitive answer is on on the Cat converter, I 've been reading and am unsure, people are saying stock ceramic cat, so are a couple of shops but 2 other shops have said to go something like a 400 cell euro 4 cat.
I don't know much about this so can anyone that has passed with a similar setup share their experience with what cat would be better or if there are any better ones to go for that would be much appreciated.
