*MAXXD* Ollie's Nissan 200SX S14a

[Roger_Sausage]

Mate, remember you've got a cat in the front pipe on an S14a too, changing the centre one on it's own may not give you what you expect. Only thing to look out for though is that when you remove both cats, the loss of restriction gives a faster turbo spool and 1-2psi more boost, so an uprated fuel pump and a set of spark plugs one grade cooler are needed.
