green stickered

[iOnic]

Tbh on a front engine 2L turbo car you don't have to do anything special to have a legal exhaust. Mild steel piping and a couple of decent mufflers/resonators and it'll be plenty quiet.

This is perfectly legal on my Evo and is barely audible in the car. Lost count of how many cops I've been past that haven't even taken a second look and WOF's are no bother. Induction noise quite easily drowns it out even though it's a full 3" exhaust from the turbo back with a "fart cannon" at the end. When Mark (1I1) came for a ride to Wellington he was quite surprised when I told him it had a full 3" exhaust

talked to cert guy today can use silence in the tip.might just go with factory exhaust.

think its a custom exhast rusty

[Mr Revhead]

You can use a silencer. As long as its not removable.
But why would you? They make the rest of the free flowing exhaust pointless

[jbod]

A silencer would really only be a way to get through the warrant, but would undo the point in an exhaust. Just got 4 new tyres which was about 800bucks as id say vtnz would fail mine, they were getting boarder line,so dont really want to do any work to the exhaust (not in the budget). think i will put the factory one on instead

Earlier this year i was helping a friend get her levin off a green sticker for exaust being too loud. I removed the exaust and put the factory system back on but when i took it to vtnz, it still failed as the guy said since the car was green stickered for the exaust being too loud, it needs to be certified even though i put the factory system back on. Not sure if this was right or the guy at vtnz was just being a dick so in th end i put old exaust back on but this time i added another resonator then got it certified.

Basically if its been stickered for exaust, it needs to be certified even you put a silencer in or put the factory exaust back. Well this is what vtnz told me.

Is this correct?

[jbod]

Yep garreth thats bang on. Tho i think ill jsut put the factory one on cant keep poring money into it allready spent enough haha . cheaper to put factory one on and get certed. than get resinator welded in and a cert

[Mr. Mainstream]

did you have a valid current wof when you were stickerd?
PM me if so, i know a trick.

Interested to hear this 'trick' because a wof is only proof that the car was up to standard at the time of testing and having one doesn't mean sh1t if the car is no longer up to standard.

Having heard your exhaust I didn't think it was too loud, no louder than my ST205 with HKS system. I think a lot of it comes down to time and place.

My 1990 MR2 GT was running 3" dump, 3" B pipe and dual 3" cans.

Used AdrenalinR stuff (based out of Hastings). Best mufflers and resonators out there and they dont cost a pile of money either.

Some propreitry 3 layer sound baffle material (steel,glass,ceramic) with Sanpro louvred tubes.

Result being near factory noise levels, more flow and nice sporty note.

Used this on MR2, and now the Legacy GT-b

GT-B has been decatted with bigger front pipe and had factory resonator removed in exchange for a AdrenalineR 300mm resonator. Sounds like factory.

Yes id say time and place richard, have been pulled over plenty of times and the exhaust hasnt been an issue. going to get a silencer tomorrow and measure it with a desabel tester and see what it comes out like, if thats enought will get the cert hopfully

[jbod]

Does a cop need to have proof that it is over the limit ? Because all he did was listen not measure it with a desabell meter

No they don't, it's all opinion.

[gt4dude]

use a phone app, if u can get 90db on ur phone, go get it certed

limit is 95db, so that should give u some margin for error.

the test is at 4000 revs in neutral, in line with the tail pipe about half a meter back from it.

[jbod]

Do you know for fact? For speeding they have to have proof which is recorded with a radar gun. So how can they guess with there ear

[gt4dude]

yes its up to the cops, they have discretionary powers when it comes to stickers. just dont floor it around cops thats when its loudest...

[duddley]

I thought the amount of revs varried between diffrent types of vehicles.

[Al]

It does. When you go for the cert testing.

Even if you get a cert the 5-0 can still green sticker your car again.

Apparently they have well calibrated ears?

Also for speeding they don't have to have proof, they can write what ever they like on the ticket (though normally write the speed you were doing), because when they stand up in court and say "I'm a police officer and he was doing XXXkm/h", and you say "I'm blah blah blah, I don't know exactly how fast I was going, but not that fast", they win. Sad but true, be thankful most of them are honest.

Is anyone aware of someone challenging the legality of a pink or green sticker?

[gt4dude]

It does. When you go for the cert testing.

Even if you get a cert the 5-0 can still green sticker your car again.

for this particular vehicle its 4000 rpm.

you're supposed to keep a copy of the cert sheet in your car, it has the full diagram of your exhaust showing everything thats in your system with lengths and diameters. if you get pulled over again you can ask him to look under your car, and compare it to the cert sheet.
