Hey. So I was about to book my car in for an OTR, mafless and exhaust system when the guy says to me that not only does the performance with an OTR and mafless vary in Victoria especially because of the ever changing weather but apparently they're illegal as well?! Does anyone know anything about any of this that could please help me out? He also said to prevent the variation you could do some head work cam. Any details or advice on anything would be greatly appreciated (including directions to take for heads and cam sizes etc).

The weather?? WTF?

OK a drag strip result may vary if you have a run in 40 degree heat compared to a 5 degree night, but seriously?

Removing the MAF is tampering with the emissions system, so yes, it is illegal, unless it is factory like the Monaro.

The dude you spoke to sounds like a muppet.

Kinda the point of a OTR is the increase airflow. Leaving the MAF in place kinda fly's in the opposite direction!

Its pointless worrying about legalities with car modding. Basically anything you do is illegal. Cat-back exhaust, tunes, anything.
