StealthX Posted May 16, 2010 Share Posted May 16, 2010 Ok correct me if I'm wrong, but isn't its pretty flawed to be testing cars in neutral? When the engine's under load obviously the exhaust note will be louder, and every engine has different load characteristics (more boost = more load etc...) Wouldn't a more accurate test be to test a car's noise under load, not in neutral? lol Good one EPA...

jjskyline79 Posted May 16, 2010 Share Posted May 16, 2010 So let me get this right If i have a EPA test on the noise from my exhaust it will fail with a stock factory fitted part??? So then what?????? Somethings not right there Link to comment https://www.sau.com.au/forums/topic/319936-the-ultimate-exhaust-sound-level-thread/page/2/#findComment-5236163 Share on other sites More sharing options...
MrStabby Posted May 16, 2010 Share Posted May 16, 2010 Somethings not right there Does anyone know if the ADM R32 GTRs had the same exhaust as JDM? Or did Nissan get some sort of low sales volume concession on the noise level issue? Otherwise I cant see how they could have sold them here legally....

R31Nismoid Posted May 16, 2010 Share Posted May 16, 2010 The EPA laws for Vic are stupid - factory cars do not pass. Just how it is.

Kinks Posted May 16, 2010 Share Posted May 16, 2010 It's hard to find a performance exhaust that is still quiet - I went for a Fujitsubo catback, metal cat and JJR bellmouth dump and it is still pretty quiet but flows a lot better than the stock system. I'm sure if you heavily modified it would pose a restriction but for light mods they are a good brand to go for. Mine has an oval centre muffler and a big oval rear muffler - there's a canon type but I'm sure it would be noisier.

Im sorry and you (not you personally) let them get away with this f**k me id be taking it as far as i could go If i had an engineers report that allowed my car to be road worthy with factory fitted exhaust and it failed an EPA noise level test later then someone or something is wrong and its not me.

Id be calling my solicitor If you can provide proof (e.g. receipts or part number on the parts) to the whole car is stock from factory I'm pretty sure you will win the case. Else, it'll just be too hard. Especially old/imports, I doubt theres one thats truly stock. Those numbers are pretty surprising. I've got the TI-R on my 33GTR (only mod is catback, cat and pfc tuned to 250awkw) and its nowhere near 95dB or maybe it wasnt tested at 5100rpm. I might test it again just to confirm next time when I'm servicing the car.

Thats cool I still have a stock exhaust (somewhere that I can put back on even do comparisons as i'm pritty sure the after market one is quieter still) and can get part numbers easy enough so that, with the engineers report/rwc should make a very interesting court case. It comes as no surprise we have similar problems back home sometimes.
