Legal Db Of My Exhaust

[PIOTREK]

I don't think that this belongs in the epa section of the vic forums, as i'm looking for opinions of ppls from past experiences.

I curious if my exhaust exceeds 90db. My set up in my R33- i'm running stock pipes from the turbo to cat- 3inch high flow cat (catsco)- 3inch turbo back exhaust (hakimoto [not sure on the spelling]).

Today I went and got the exhaust lifted to ensure that my car is legal ride height and they didn't have a db reader. I'm currently trying to tidy up any loose end to avoid and surprises further down the track, not really looking for fines either lol

If ppl have facts of this issue, i'm keen to hear your thoughts.

Thanks

well i just cleared my EPA last week. 3.5" dump which i then bolted a stock cat back exhaust onto and my reading was 87db

seeing as you have changed from the cat back there is no way you will be at 90db or under.

[PIOTREK]

Lol is it really that easy to exceed it? must agmit my car is not really loud but sure is not stock sounding either

Bit hard to imagine what your exhaust will sound like

How many mufflers all up?

Got a vid?

[krzysiu]

90db is VERY quiet. With what you described it would probably fail an EPA.

2 mufflers- It isn't TOO loud or draining either i reckon i will try and get a video together.

Two mufflers should be alright. It's a qualitative measure so I'll wait to hear the vid but you should be right. I've got one muffler and a hotdog, it's alot louder than stock and the cop didn't say anything about my exhaust when I got pulled over for inspection.

[PIOTREK]

thanks birds,

i think it should be fine, although i stuck a silencer in just to see what it sounds like- still need to take it for a driver and check. But i strongly agree that it is qualitative measure.

Without a dB reader, all this is speculation.

Take it somewhere, get it tested. No one can tell you.

Where did you get your exhaust lifted? and what part can get tucked up?

i'm pretty clueless to this stuff..but last time I was at my mechanics getting other stuff made legal, i asked him if he had a wheel to measure ride height. The entire car was clear except the middle exhaust bit that hangs down right under where you sit, it just clips his measuring tool a little and gets stuck. is there anything that can be done about that or should i be looking at suspension, not exhaust?

[Birds]

You can get any part lifted up as long as there's enough space between the pipe and the chassis. They'll just put a small mandrel bend in either side of the part that is too low. Alternatively, if you have coilovers you can just raise the car a quarter of an inch lol.

Cheers Birds, I'll get onto that.. any recommendations of a place to do it though.

Peter where'd you do yours? And where are you heading to get the DB sorted out and tested? shouldn't a mechanic or a wide number of places have these? if so, i wouldn't mind knowing my own reading. keep us updated on the outcome.

[alr33x]

yeh shanus u can get it tucked no problem.

birds do not suggest raising the car that is blasphemy!

[alr33x]

tidd brothers in spotswood can do a noise test but lots of places can im sure..same with tucking any exhaust shop worth their salt can do it

[Russman]

Just get it tested when you get an EPA.

Seriously 90db is rediculously quiet.

Your solution - http://www.nengun.com/fujitsubo/legalis-r

No power loss, just noise loss

[Birds]

Quiet alr33x you hellaflush fool.

Any exhaust place will be able to do it for you mate. Ringwood performance exhaust were pretty good when I got mine done there.

lol @ "Legalis", funny as name.

[boostn0199]

Its doubtful that if its aftermarket exhust it will pass the stock r33 cat back is pretty borderline to legal ranging form like 86-90 and thats real quiet so doubtful any aftermarket would pass , can come close though

[ashneel]

there is no such thing as a legal aftermarket exhaust.

so any change you have made to your exhaust is illegal and you will feel EPA

[alr33x]

mine got tested with stock 33 exhaust and was 86db...

wheres the love birds honestly? u know im right
