I am thinking of taking cats off or if you people could recommend a good tester I'll go there.

I went to tester in Notting hill.

how much for a test? I don't have faith in this tester.... I heard it when you had this setup before your exhaust and it was not loud... I can't understand it

Yeah I can't understand either. It's so quiet you can't even hear the bloody thing.

And $38 for the test. Epic waste of money.

This can't be man lol I don't know what to tell you but I personally would take another test elsewhere after hearing it... Maybe that's just me cos I'd be (and am) pissed off about this situation lol but then again the $40 odd might go better towards returning cats to stock.... sigh... I still think it's a load of crap

That's really crap waqar! I tell you what though, yours is the 2nd Epa letter I've been told of in a week. Really gets me worried to even have a cbe...

A run of bad luck down in Melbourne guys
 

Sounds like you're having a tough time down there with the mods to our gorgeous 370z Exhaust systems....what pisses me off is the shitty Commodore & Falcon V8's with their "Hotdogs etc" rumbling & screaming everywhere with their "Corny" sounds and yet the authorities are nailing a well tuned "musical instrument" such as the 370 zeeeees.....exhaust note..... !!! No Contest...!!

I Feel for ya guys I really do.....!! Sometimes there is no Justice....Haven't the cops got better things to do....like catch rapist's / murderers / and criminals...!! Obviously not.. A well tuned 370Z exhaust is obviously out of the question and should be eradicated at all cost...!!. All hands on deck to shut it down.....
Give the cops some 370Z's as patrol cars and I bet they change their minds.......INSTANTLY....

Hey Melbourne Crew

I will be down for the cruise on the 23rd, I work in the sound production and entertainment industry and of course I have a SPL meter to please our NSW EPA kill joys. Well if someone will get the info below I am happy to measure all the cars there using the specification the EPA would use. I would start off with a baseline stock with stock CATs then measure all variations. If someone asked me nicely once back home I could start a thread to post the results of each of the variations at the cruise for the guys in other states. But be aware as normal each state will have their own test specifications, you will need to do some research to get meaningful results.

I need to know the following and I am sure it would be outlined somewhere in the Vic EPA website or by asking them or a tester. I have looked and I am close but no cigar.

- Environment of the test eg inside or outside or what space.
- At what engine revs it seems like 75% of red line eg 5250 rpm
- At what distance, position and angle from the car is the measurement taken eg 1m right angle from the rear of the passenger side of the car.
- Confirm the test routine increase engine revs to max and reduce over what time eg increase over tens second, hold at max for 5 seconds and reduce by foot off throttle pedel over three seconds.
- Confirm the test measurement type eg SPL A weighted averaged or peak rms over how many seconds.
- Confirm the max SPL is 90dBA

I would be about accurate to a 2% tolerance with my small meter because that is all a can pack in my bag. All I need is some time on the cruise at one of the stops to take the readings (about 3 mins each) and collate the info.

Your call Melbourne guys, tell me if you want some comparative measurements for peace of mind on your mods. I am happy to help others that love this car, oh also I love Michel's lattes two sugars with toasted banana bread with butter but no cream.:tiphat:

Yeah that would be great!! I had downloaded the specifications for the test a while ago but seem to have lost it. I can get them again no problems. It would be interesting to see what the results would be.

We can discuss the findings in greater detail over a coffee haha.

See you there, look for the little guy with the meter and the lab coat maybe he really is an EPA guy you never know, take a chance.:eekdance:

Tony from FI has convinced me to retain my original order with the Resonated HFCs..
I should have it in the next few weeks!!!

U'll be right with that set up.

I wanna hear resonated HFC's with 12 res cat back!

Oh and your feedback helped too btw.

Yeah our cops suck here in Melbourne. most of them that i have seen are fat slobs with bad attitudes and 5 foot nothing police women that could not apprehend a 10 year old. Oh, what they are interested in is catching drivers who go over 3km/h the speed limit. Road side revenue raisers!

Nanny state
