Wat Do Epa Check For?

[ZILR-34]

hi everyone

i dont know if this is the right section to post this but yea...

durring the week when i was driving to work in my R32 gts-t i got pulled over from the cops. (i wasnt doin anything bad and my car is completely stock part from the cat back Exhaust.) anyways they were lookin over my car trying to pin sumthing on me. anyways they said my Exhaust is to loud and ill have to goto the EPA to get it tested etc..

my question is if i put my Silencer in the cannon and use low octane fuel (91 RON or lower) will this pass the EPA Emissions tests? also the cop said if i put the Silencer in ill have to get it welded up. or should i just but a Standard 1"inch Muffler just for that day?

post ur comments wat u think

cheers

I reckon the 91ron or lower is not worth it cause you can cause some damage to your engine plus you will run richer aswell so hence make your chances of them pinning something on you even worse. The silencer would be fine the same cop wont be at the epa station so i believe it would be all good as i know people who have the bolted silencer and never had a prob.

Did the cop say you MUST GO TO EPA, or did he say a "licenced exhaust tester". Because if he is only giving you an EPA for noise then all you have to do is go down to the closest exhaust shop listed on the EPA noise letter and get it noise tested. And if you have to put a silencer in it MUST be welded in to pass, but sometimes if you know the guy some rules are bent .

IMO it's probably easier to swap to a stock exhaust for the test.

I also don't see how 91RON fuel is going to help with emissions.

[Topstage_S14]

off to Daalders you go

[R31Nismoid]

chaning fuel does not alter emissions when the ECU is looking for over 100ron anyway

It'll be a test, just going to a licensed tester, not the EPA station itself.

Get it tested, see how loud it is

go from there

simple

i went to Daalders last thursday to get my exhaust checked and yes they will make u take out ur baffle if u have one in unless its welded in there, they arent stupid

[TracidTrax]

oh and the guy at Daalders said to me if u need the noise test only for RWC then he can do with baffle/silencer in

[Ruffels]

EPA is fun

belive it or not skylines run very low emitions

you'll pass emissions EASY

however noise is your problem...

bolting the silencer into the cannon is not good enough, when i failed noise at epa, i asked them if putting my silencer in there is good enough.. and they said no... only if it is completly welded in there.... and spot welding it a couple of times around the rim isnt good enough either!

you should be right...

all the cop said is that ill be getting a letter in the mail from the EPA to go for a test. i dont really want to weld up the silencer to my cannon it looks sh!t and it sounds G.A.Y, but when using 98+ ron doesnt it burn more fuel and create more emissions?

[Ruffels]

no way.. skylines are tuned for japanese fuel (like 104oct) so its fine.. emmisions shouldnt be your worry.. your allowed 5% carbon monoxcide or what ever it was.. i had a screwed 02 sensor and still only blew 1.6%

WAY under

you'll be fine

... with sound just make a baffel plate with a few holes in it and jam it between one fo your flanges

they rev skylines upto 4800rpm at epa and it cant exceed 90db

Not a problem. You just go down to a licensed epa exhaust shop. They will do the test. When you pass they give you a certificate, they keep one copy and send it to the epa saying you passed. Thats it.

DO what ash advised me to do. Get a mufler made up that decreases the diameter and just with a normal muffler. Lowered my car from 111DB to 89DB to just pass. And when u get home. Chuck the cannon back on

takes about 20mins

is that for all skylines? i thought it depends on the engine. They did mine at 4200RPM - 2JZ-GTE

[R31Nismoid]

its motor dependant

RB26 is 5200rpm

RB20 is less than RB25 if i recall

[Ruffels]

well they reved my r33 upto 4800

^^^ probsbly right.. rb20 would be less

[ali-turko]

whne i gont done for noise in my gtr i went to daalder they my car wouldnt pass so they made up a little muffler with flanges to connet up to my 3.5 inch exhaust, so i can tkae it on off when ever i like, it cost me bout $180
