hi guys,
just recently bought a 3" xforce high flow cat for my r33 25t.
i thought this was just going to be a straight bolt on replacement of my stock cat..
i just realised my stock cat has a plug on it... think its my oxygen sensor
the cat i just bought doesnt have a plug for it to be screwed on... what do i do?
do i need that sensor on it? i already have one on the dumpipe?
i was hoping to install this asap until i realised it?
any ideas?
