EPA Noise Test

Hi guys,

Wondering if anyone has had any experience with this?
I've got an Akra Evo setup on my e92 and received the letter just today.

Either the spotter is retarded or something, because M3s do not emit the same sounds as a 320i, and I'm sure Akra ain't much louder than stock.

Not to mention, my previous Z4M with ACS exhaust was actually louder and it never caused an issue.

What are you talking about ... what test, from whom and what the relation to a 320 is?

Lol. Lost in the morning ey? EPA noise test. Where the gov deems
Your exhaust noise is too loud and u gotta get it tested.

Relation to 320i is gov noobs should look at the model of the car before issuing notices. U can't expect M cars to be quiet. Much like AMGs and exotics...

Think it's regardless what car make it is? If the exhaust noise is >95db iirc, they'll get you for that (and we know the cars like the c63 amg's are not quiet cars on WOT so not sure how they even rollout of the dealers)

Do you have the wireless flap controller on your Akra? Just keep it closed and you should get through?

Sucks that EPA is spotting and issuing notices. Not good news for me when I'm planning to put on the BMWPE for my ride

Let us know how you go.

90? Akra probably over that. And no, don't have flap.

Shot an email to SouthernBM see if they know anything. Stupid really as there are a number of Akra owners around....

Is this a VIC thing? What a PITA, akra is pretty tame too, but prob just over the limit at WOT. Without being a smart ass, can you write to them and contest it based on an incorrect report?

A heap of cars would be over the legal limit straight off the showroom floor....

Its normally measured as a drive by volume at a certain pre-determined speed, not WOT!

Been EPA'd for my WRX. Took it to any VACC certified exhaust shop for testing at like 5k RPM at a set distance I think around 1.5m

Akra would probably be on that limit for the slip-ons anyway. I'm going to get a dB meter so can measure mine when it's fitted

*Note this does not count if you get sent to Macloud for the full emissions testing. Mine was reported by an officer who 'observed' it to be too loud.

Totti is spot on with the level, it is 90dB. Eisenmann are the only company that publish sound pressure levels and they are:
Eisenmannn SPORT Version for the BMW M3 (e92):
Decibels (stationary vehicle): 92 dB at 6,225 RPM
Eisenmann RACE Version for the BMW M3 (e92):
Decibels (stationary vehicle): 102 dB at 6,225 RPM
Even the sport which is quite tame is well over the legal limit. The rule of thumb is if it sounds good itís illegal, if it tastes good its fattening or bad for your liver.
The Akrapovic is substantially louder than the Eisenmann sport and will probably test around 95dB, but the problems donít end there. Any system that is a full replacement system has high flow or no cats. The Akra Evo has 100 cpsi (cells per square inch) cats, stock is around 600-700cpsi. This means it will also fail emissions test and why you get CEL if you donít install a delete-R or get a tune.
Bottom line is that virtually any aftermarket system will fail noise levels and if a full system replacing the OEM cats will fail emissions.
So if itís a fine just pay and be glad, if you are going to be called in for a full inspection I would fit the stock system first and get it tested, then revert back to your Akra and hope it doesnít happen again
We all love our exhaust systems and they make a huge difference to the driving pleasure of the car but if you live in a nanny state thatís what happens. We have roadside inspections here and if you get hauled in to one of those it would be a defect notice, although they usually save their harassment for young guys driving skylines or similar.
By the way, sound pressure level apps on phones, they don't work as the microphone on your phone can't measure the high levels. You have to spend a lot of money on a dB meter and set up properly to prove what you already know

I got one in my E36 the day I was driving around just before Dutton Rally one year. Just took it to the Spotswood exhaust place, got tested, passed and went on my way.

This is the first I've heard. Nothing of that sort in the wild west.

Having said that, how do cars like the Fezas and the Lambos comply with ADR? You can hear these cars miles away with their stock standard exhausts, which means none of these cars can bve sold in Australia. I think this is another Vic government money making scam.

Correct me here, I've heard that you can't own personal plats in NSW or Vic, you can only lease them. In WA, the personal plates are register to you, and if you want you can on sell them.

In that case 90 poer cent of the motor bikes should not be on the road ... they are so ..... loud.

Was gonna it tested today, but it's raining so they can't test under those conditions.
I'm going to revert back to stock for the test. Was testing with an iPhone app according to the ADR specs - idle was at 80dbs and at 4000 rpms, it was sitting around 92db. Given the inaccuracy of iPhone apps, an actual test would pull higher.

Re: Exotics and even AMG - apparently if it comes out of the factory loud, then EPA can't fine you for it. Was told this by one of the licensed testers - AMGs come out loud, and their limit is 105 for EPA purposes.....

Double standards much?

It seems you might have to invest in a hoist. What an outrage, just because of a few problems with hoons everyone gets targeted. If you really need to find out your dB levels, you can always visit a Jaycar store and try out a higher end dB meter. The guys in those stores are pretty good and won't mind demonstrating one.

I tested an Akra when I had one on my car and I think it was 95-96dB at 5K RPM so your decision is very wise to do a temporary swap and it may avoid a further test if you get pinged in future.

Good luck and let is all know the outcome.
