Proof That Bnr32 Exhaust Are Free-flow ?

[cobrAA]

Hi there,

Here in Canada, there's a big controversy about exhaust and police ticket. So I was wondering if you, in Australia, had a proof that the BNR32 came free-flow from the factory??

I can pay $$ someone for info. But I already have a pictures of a stock exhaust but I need to make it certified..

Anyways, if you don't have direct info do you know where I could ask for? where I could search

haha um what do you mean free flow? they came out with a catalytic converter and mufflers from the factory if thats what you're asking...

yes, tell us more information about what this "free flow" law of yours is...

in aust, Its the sound that annoys the cops & the public. and once they issue you with a ticket... they can check the Toxic emissions from the exhaust if the catalytic converter looks tampered. The GTR cat im pretty sure is a 3-way cat.. as in it reduces nitrogen oxides, reduces cabon monoxide & hydrocarbons.

Free flow exhausts are usually aftermarket without a restrictive pipe in the rear muffler.

High flow aftermarket cats are sometimes a defect here.

anyways, let us know what you think

Perhaps he means "can i get by on a standard diameter exhaust"

My bad. I wasn't clear.

In my province, they don't ask for a toxic/emission test. So this it not an issue. The cop generally pull you over because you have a 3 inch tip or more, it's chromed, you have a tuned car, your young, you have a sexy girlfriend etc etc lol.

Once they pull you over, 90% of the times, they will just insert a stick in your exhaust and if it goes deeper than 30 inch, it's a proof that you are STRAIGHT PIPE ( And in their mind Straight Pipe=ILLEGAL). So I would like something certified so I keep it in my car and show to the cops that a BNR32 came straight pipe OEM.

Now, My exhaust is a RS*R ExMag GT2 ( which is the top dog of Rs*R) and found that there seems to be no catalyser under my GTR. Since a stock GTR came with a catalyser, I would still lost in court for having modified my exhaust and not keeping the OEM SPEC. But, my chances are the police officer won't know about the catalyser.

Law #94 say:

Changing the muffler or exhaust system that makes it noisier than the original OEM (1. cop don't have a Decibel meter with them and skyline didn't exist in Noth-america, so they can't give me that. But still, some assh*le do.. and now I have to prove that the OEM wasn't making more noise.)

Law #91 say:

Any repair or swap done to the exhaust,catalyser,pipe etc. can be done BUT has to maintain the same spec of the OEM.
