Default Dump exhaust at diff??

Is it illegal to dump the exhaust at the diff??

I thought the law was, the exhaust must exit past the rear most opening window... Meaning dumping at diff = legal?

My exhaust rubber broke & dropped my exhaust on my diff and crimped it down to under 1" and its crackling real bad an running real ****.. I cant afford a new exhaust.....

Cheers

Yeah as far as I knew it had to be over the diff, but I don't know by how far.

You wouldn't be paying for a new exhaust if you took that in though, they'd be able to do something for you. Do you have a muffler at the rear that youd be losing if you chop it anyway?

I know on utes its legal, not sure on sedans because as far as im aware it had to pass the rear bumper to prevent exhaust gases entering in the boot.

Thats what ive heard anyway.

i'm sure greenfoam looked into this a while ago and the conclusion was that it had to exit after the boot cause there are vents in the side of the boot which could possibly allow fumes into the passenger cabin etc. i'm putting slip joints on the V8 after the flowmaster mufflers so on track days i can drop the exhaust after the mufflers befor the diff etc. might just leave em off and only fit em for the WOF but i'm sure thats not legal here either but it's only goingto be a toy car so it's not going to be driven every dya anyways

Any thing non standard is a defect,Dumped at the diff wouldn't be legal in my view i would contact Transport s.a or the such in your state and ask them.

the 40cm sounds familiar to me also, just call vic roads and see what they say.

i think the term is that it has to be x mm away from the last passenger compartment or something like that.

As long as you exhaust comes out behind the rear most opening window, it's not too loud, it clears the tyres by at least 30mm and you don't remove a catalytic converter, it should be legal.

Check out the pdf linked by Bax. The short answer is nope. There are 2 reasons - You will be deleting 1 muffler which will mean your car is probably too loud plus the exhaust gasses could fill the boot area and in turn circulate into the passenger compartment giving you a nice sleepy feeling.

Nope. The vehicle standards pdf says no such thing. When are you guys going to research your posts before you hand out half arsed advise? It says that the outlet must be 40mm behind the rear most joint in the floor pan that is not continuously welded or permanently sealed. In the VN there are some vents in the boot which are not sealed and thus does not satisfy the "permanently sealed" requirement.
