wat bout adjustable silencers? they legal?

silencers have to be welded in. you can buy adjustable ones which can be controlled from inside the cabin and the valve opens and closes hence less/ more noise but you can still get caught and you will still have to change it.

i personally think silencers welded into an exhaust pipe look gay and defeat the purpose of having an aftermarket exhaust in the first place.

ronin09 dont weld one into your exhaust pipe!

maybe look at getting something welded into the exhaust eg another muffler or maybe about 20 resinators ;) maybe we could swap exhausts :D no no swap rear mufflers :) then you wouldnt get any hassels! :)

yes, as akeenan is saying.. any form of "artifical restrictor" is illegal. The test place was telling me all about that. Bullshit but true.

I believe the "restrictor" rule is to precisely stop what we are suggesting, and that is have it silent one minute, noisy the next. Imagine how much trouble you could get up to with that..

I have the bolt in silencer, but it lives in the cavity next to the jack. The thing with having the silencer in all the time is you're less likely to attract attention whilst just cruising along; and thus less likely to get sent a notice.

Akeenan, i am SO not welding nothin in my exhaust!!! I have however heard a good trick if you want to quieten up an exhaust for either EPA test or EPA @ Macloud -

Get a piece of 3mm aluminium (offcuts from Capral are perfect, all of about 2 bucks), cut it to the exact size of the flange that joins the cat to the rear section of your exhaust. Drill the holes accordingly, and drill about 3 - 4 1cm diameter holes in the plate, then simply bolt in between the cat and the cat back section. When done, remove. Simple. No welding or cutting, no need to buy an additional muffler... But alas, V-bands mean i can't do this ;)

Oh yeah, i have a complete STOCK exhaust if anyone ever needs it - i am so not putting it on for the noise test though, we'll have to "sort something else out" :wave:

hehe welcome to the club ronin.

just chuck your stock exhaust on and take it for the test at the epa station, that way when the epa pases u even if a cop reports u they have to provide evidence not just say they estimate it to loud or some other BS before the epa will call u back.

they have to provide evidence not just say they estimate it to loud

believe you me haha.. you dont have to estimate you know straight away that these systems will be above way above the 90db. these make inarks girlfriends exhaust noise look pathetic. and her car is loud :)

I have a friend who just received an EPA notice as well,

He has a GTS-T Mspec (great car). We have both tried to find an exhaust place who will make a silencer, but so far they all say its too hard !! I was thinking of getting one for my car too, save me chasing one in the future.

Does anybody know an exhaust place that has made one or is at least willing to try ??

Klokan: Is it a noise EPA or full EPA at McLeod?

Canadian GTR: slack asses who don't know their stuff.. get them to either replace the resonator or put a silencer in.. daaler exhausts - 500 Station Street, Box Hill should be able to help you (this has been discussed in recent threads to death)

got my first one today....

it is only a noise one and as i only have a HKS cat back i am hoping it will be under...

i am thinking of going to daalder in dandenong....

if any ideas or suggestions please drop a line...

daaler exhausts - 500 Station Street, Box Hill

has anyone tryed there resonator that they claim it will be under 90db

i just got my exhuast system and it is a bit loud in low revs

as i cruise its really not that loud just mainly hums

but when i boot it the exhuast gets very loud

im thinking of going down to daddler exhuast's ( Box Hill ) to buy the resonator and fitting it in myself

    • It's all about selling non-compliant emmisions stuff, and things like tuning stuff that makes your car have more emmisions, a very small percentage of modifications and tuning go into race cars, the vast majority of tuning and mods, like catless exhausts, or non-compliant cats, go into street cars with registration  Like a gun shop can only sell to someone with a gun licence, if they don't, they are fined and even jailed, and whilst a gun is totally different to a tune, or a catless exhaust, they are still illegal for a street car As for customers, it easy, they send a letter and tell them to show up for an inspection, like if someone says your car is to loud now, if they don't show up for the test, they can cancel rego, just like not paying a traffic fine This has been happening for years overseas in other countries  I'm in no way happy about it, but, I think there is definitely writing on the wall for modern cars with emissions standards, which will effect tuning shops, parts suppliers and end users And like other countries around the world, it is the government's that makes the rules and regulations for street cars with rego What would happen to a tuner or workshop if they were investigated about turning off stuff in a ECU IRT emmisions stuff like engine check lights for cats, or removing cats, or putting in a lower cell cat, this is apparently all illegal IAW modifications to registered cars, or, retuning the car so that with even stock emmision stuff still installed, but due to the tuning, or parts, like bigger cam shafts, it will now not pass the emmisions test Yes, I am going into a rabbit hole, but going off what other countries are doing IRT everything related to emmisions........cars, trucks, manufacturing, mining, modified vehicles are a easy target Meh, time will tell how it goes either way 
    • This^^^ 100%. Endless Male Attention. "buy a cool car, attract females". No reality is the opposite. "Buy a cool car, attract males".     
    • Just wanted to share the recent dyno results on my car. 20lbs of boost on pump gas. Pulled the fuse on the AWD so it was only rear wheels on the dyno. It made 484 hp at the wheels. I asked the tuner to see if we could do something so it breaks the 500hp level, but he said that we were maxxed out on pump gas. If i wanted to make more power, id have to go to E85.      8739a97a-9408-4eeb-b769-108ff1678736.mp4
    • While there is no current law for the spoon, let's swap to a different utensil. Example, does the store get fined for selling a butter knife if it ends up being a murder weapon? Perhaps they cpuld be done for assisting if they *knew* it was going to be for such a purpose. But, if used properly, which was its primary design, it's a tool for a job that's legal. I could understand companies being prosecuted if they advertise their products for being road legal if they in fact, are not. Possibly, but not necessarily, the tuners for tuning a car to a non legal fashion(emissions), but there is always the possibility that the customer really doesn't intend to use the car, in that configuration, on the road. So long as the companies can prove they have conveyed how illegal it is to use the now illegal car, in a place where the vehicle must meet the laws, they shouldn't be punished. Not sure about other countries or states, but I've been made aware that I can't legally stop a client from taking and driving their own car in NSW, Australia, even if they owe the shop money. It must go through court to get the funds from the customer, and you need to get the police or roads covering body representatives to come and stop the owner from driving the car, even if I know how hazardous the vehicle is.
    • probably around the $1700-1800 fitted in his sizes.  The ar1 is heaps cheaper. Get on scumplace I got some A052 295/35/18 for $400 that had done maybe 20-25 hot laps of SMP.
