Clearing EPA, how do they usually test it?

[WATAJK]

put OEM muffler and you'll pass no dramas mate. My Ford Laser SR2 got rev'd up to 4800rpm, i'd say our dc5's would be similar...

[dougie_504]

Twinloop should be rather quiet so I think you'll pass personally.

Makes me wonder how motorbikes get away with it, don't you think? I know they're difference vehicles, but they're f'ing loud compared to cars, yet apparently legal...

WATAJK Your location is in VIC .

The Epa test .
they check it a few different ways - on acceleration, deceleration and on idle. levels depend on the age and type of car.
i have heard of people stuffing steel wool in the muffler for the testing to make it quiet and then removing it later.
Sometimes they even have the stock system at home and the swap it prior to going in for the testing.


friend car had been

My car was waaaay over (std dump, 3" stainless front pipe, 3" Metal Cat and BuddyClub Spec3 cat back, no resonator small can) so I left it from the cat and put the standard cat back on.

I had to replace a rusty resonator before it passed, and it still wasnt that far under (max is 90dB for cars)

The test sheet shows
Max level (including backoff) - 88dB(A)
Noise at test speed - 86 dB(A) @ 4800RP/M

Make you wonder is it ever worth going for name brand headers, mufflers to get dik'd.

Yes that is what I thought. The twinloop is pretty much the same volume as OEM muffler. Although I'm just going to bolt the OEM catback just to be safe.

Thanks mate!

That article is a a crack up.

Operation Pipedown is a traffic operation conducted by Victoria Police in partnership with the Environment Protection Authority, Melbourne City Council, Melbourne University, the Victorian Deaf Society and, interestingly, Harley Davidson.

Maybe that's why they don't target Harley's! Ozhonda should get in on this partnership business so they don't pick on us!

how does the deaf society have beef with loud cars? ...

I got EPA'd in my em1, they rev'd my car to 4k for testing, cleared it even with a canon you should be sweet with a twin loop.

[GSi_PSi]

This is where a aftermarket ECU is best lol. My mate got EPA'd once he set his launch control to 3,200rpm, tester couldnt go any higher lol cleared.
Also got pulled over by Cops in my DC2 and they were testing the loudness of my exhaust and was hitting the launch control at 3,500rpm lol
they went on their merry little way after that.

From personal experience

With Toda Headers, High Flow Cat, and a Mugen Twin Loop, you will not pass.

With Toda Headers, High Flow Cat, and a Mugen B pipe with a stock Muffler you will not pass.

With Toda Headers, High Flow Cat, and a stock B pipe and stock Muffler you will not pass.

The Mugen twin loop is not the same in volume as the stock exhaust.

Your headers and HFC will kill you for DB.

They rev you car to the limit, 5500RPM and upon backoff you will spike to 92db.

You need this, then you can bolt it up to a 3" de-cat and you'll pass.

I may have had a tough guy conducting the test but that's my experience...take from it what you wishhhhhhhhhhhhh

[Lukey]

got off this first one.

[lemmiwinks]

I'm trying to find someone in Melb with stock DC5R headers, but haven't had much luck. Anyone know where I can get one / borrow?

Bungsai - Where did you get yours tested?

Lukey - Thanks for that! Now I know what I'll be looking out for in the mail :P. How did you find daalder exhausts? Lenient?

Do you have to take in the Certificate of compliance in person? Or can I just mail it in?

[Lukey]

they were alright, dunno if they are lenient as i swapped back to my stock catback.

and you just mail the white copy off to the epa and keep the yellow copy

[baby_phantom]

wow now im worried i was planning on getting- well still am Toda headers < comes with no cat , and skunk2 mega power r 70mm cat-back lol for a ep3r, whats the chance of getting epa'd in nsw also is it true will u get a on the spot fine of 5-10k or could i say i didn't know i just bought the exhaust online as a package and wasn't aware that its illegal. Or do they tell u to go get it tested thus having time to put the stock one back on.?
