Anyone running catless headers in NSW?
 

Just wondering cause I'm running catless header and E85 with OFT tune and I doubt my car would pass emissions fully.
Trying to either figure out if I need to chuck another cat in, or if my worries can be eased.

Mainly worried about the potential for being sent directly to a testing center without a change to swap back to stock or change my tune beforehand

You’re in the same boat as me except I am turbocharged [emoji23]

E85 runs cleaner and you still have one 200 cell cat in the stock front pipe? Don’t think it will pass if you have a tune on it as the E85 tune takes into account that you have a catless header. Adding a cat still wouldn’t make you pass unless you tune for it.

Similarly I have one cat and am turbocharged, but if I add another cat without detuning for it I will still fail emissions
