How whould a 2inch cat be on full stage2 200sx s13 ca18det ?
Only thing I got a gt28r.

I will need it for drift competition its FIA approved, it costs 1/4 of a 100cells 3" cat what should i do?

You'd have to try it and see - I've not tested that map with a cat. Check the fuelling and that the engine isn't detonating :)

guess i have to buy the expensive £280 3" highflow cat to be on the safe side, we in sweden has a strict rule that we need to have FIA approved cats in every competition on all circut racing etc, only some classes dont have it (nitro funny car etc).

Tobad.....but thats the way it is :( we have much more rules than UK have regarding safty aswell.
