i dont know about everyone else but we just take the catalytic converter off and ram a bar through it and knock out the catalyst... its not legal but it works and skylines run very clean even without a cat, so even if they bring out road side emmision testing it will still pass.

dude i emission tested my own vehicle, i saw the figures with my own eyes, not to mention everyone else in the workshop. i wouldn't say it if it wasnt true.. the skylines do run very clean even without a catalytic converter as long as you are running standard management your fine... its not like im going out telling people to do it that way thats just how i did it and it works for me

my exhaust guy told me if ur caught without the cat theres something like a $10,000 fine... im pretty sure thats true in melbourne.

safer to just get a hi-flow cat... dunno if its as good though as taking it out completely. but I dont wanna sell my car to pay a fine.

True. In Vic you risk a $10k fine for no cat.

There is no way in hell a catless skyline could pass emissions. Even my nose could tell you that.

    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
