Epa Exhaust Decibel Test

[Johnny]

Hey guys,

yesterday i got a letter in the mail saying that on 11th november someone noticed my car may have a too loud exhaust and i now must get a decibel test at an approved place to gain a certificate to send back to the EPA to avoid a fine.

Now im glad its not a full EPA inspection but ive never heard of anything like this before; although it seems pretty straight forward.

Has anyone ever gone through this process before?

I hope i will pass considering my exhaust isnt very loud at all so i may just have to slip a 50 to the tester to pass me anyways lolz.

[AGE]

Yep.... i've had 3 tests

[Gazzilla]

Yep, had a full test, but before I went in I replaced my 4" Apexi to a 2" pee shooter. On another Note, I think you will have to slip him atleast $100, as most testers are douche bags.

One more reason I keep my stock zorst in the shed

^^ true that...but my 2.5" kakimoto catback still past aswell as it is jasma. i do have 3" dump and front though with standard cat. i'm pretty sure u'll have to change or find someway to quieten ur exhast if its got a 3" or more pipe. if u have 2 big ass mufflers in between should be o.k but otherwise could be to loud.

although if u get it done, u pay the tester and then u fail, just like a rwc get it fixed up and tested again without the charge within a specified amount of time i think. gotta be under 90 decibels.

[Johnny]

Wow thanks for the responses guys, so 90db is the limit ey!

I have a 3inch pipe; im counting on 2 turbos, a stock cat, mid muffler and rear muffler to be enough as i dont have a stock exhaust!!!

might have to pick one up asap if i dont pass, then again gazza i may just slip him 100bux; cbf fucccckn round.

stock ones register 80ish plus dont they? so ave yourself the trouble of paying for two tests and just wack a cat back stocker on. Some places will see that you have a stocker and wont bother pulling the machine out to test. Those are the places to go to. What sucks with the test is that cause of the engine size or whatever they have to rev it to 5k.

[jakez88]

lol u could probably pickup a stock 34 exhaust for $100? or am i jsut thinking that they are because 32 exhausts are around that? lolz

Just went though this whole load of shit, all the guy's that tested my car were pricks I tested 2 Db over and still he would'nt let me off pricks like I said.

Thanks man i appreaciate it; will try first and pm you back soon

i can imagine them being pricks but ill see if i can bribe them first......money talks!!!

[jakez88]

lolz don't go 100 though man..don't think its worth it...u can get a stock exhaust...try $50...if he's playin hard to get offer him sex

[Stock GTR]

Yeah, don't think the 100 is going to cut it. Worst thing is, a stock exhaust wont cut it. A few years back they changed the rules. Instead of testing cars at 4000rpm or so, they decided to go for engines at around 2/3 of there RPM range. That means that a stock GTR is not street legal. A standard exhaust will still need a few extra baffles/mufflers.

By the way, the money talks website is awesome. Not that I google this sort of thing.

[RBPOWA-(TJ)]

i got a stock exhaust off my stagea. same shit i think just untill the diff..

getting my mid muffler cut out on tuesday also, cant hear that RB note. cant even hear my exhaust as is now. full 3inch.

interested in muffler borrowing ?

[Johnny]

Wow the epa are really a bunch of communist fagz!

i dunno how im gonna get outta this one but maybe if i wear a hannibal facemask and scare the shit outta him, he might pass me lolz

na money bribe is the only way, that and set my rev limiter to 3000rpm

Anyone selling a stock r34 gtr zorst? ill put a thread in the WTB section.

If yur gona try and bribe em dont bother I got the bolt on exhaust and test done for 170ish the test cost 39bucks so you might as well just buy the end section and be done with it, and have it ready to bolt on for the next time you get done!!!!

I had mine done in Ringwood check the list of aproved tester's and you should find them I cant remember the name of the joint but I was in and out in about 2.5 hour well worth you doing hope this helps

[llama_au]

^ Was it Ace Exhausts or Performance Exhausts? Ace Exhausts have always looked after me. They're an approved noise tester and are happy to tell you if your car's too noisy to pass before they do the test

They are mearly doing thier job.

Ive got a full 3.5" exhaust, that passed under 90dB, so well made, there isnt a problem with flow & noise.

1. You cant limit your RPM. If you do that, you'll instantly fail because the car is not testable.

2. Bribe money wont work either, its a contact arrangement for testers, they get caught fudging they are fined and loose the license.

3. RPM test is 5200rpm for the RB26, and backoff noise is also noted/recorded these days.

4. They write down the makeup of the exhaust. If you put a stocker on, they will note that down. If you are busted again, and again with an aftermarket one but keep appeared with the stock one... a full EPA will come in the mail with a please explain

Other than that - there is a full EPA thread @ the top of this section.

The teat costs 40bux i think it said in the letter; i will pop my compliance cat in and see if it passes right off the bat, maybe i can get my tacho recalibrated to register higher eg: 500rpm advance

i will try to bribe them though as it has worked for me in the past at other places but hopefully it wont be needed, my zorst is just catback and quite chunky so i think it should be ok.

To stop this happening in future ill have another hotdog or midmuffler installed asap. Might also pickup a db meter off ebay and see what it picks up, that way i can lend it out to anyone who wants to do a home test.

UPDATE

just bought a dB meter of my own which i should get in 2-3 days.

anyone can feel free to come to my place and do a test if you get a letter in the mail or just wanna make sure your cars legal.

oh and to make sure the exhaust shop dosent try to lie to you; its accurate 2dB +/- at 134dB
