Golgo fails EPA noise test with flying colours!


Recommended Posts

OK - so if I had read 91dB, I would have been cross, so to prepare, I fitted a CAT (thanks Gerald) and prayed to JASMA hoping for a legal pass...

97.8dB @ 5400 rpm!

Worth doing, worth doing properly :)

I think that's something like 6x louder than it should be?

The tester liked my titanium system, didn't charge me for the test - and said come back with a stock system for a big tick.

So... does a GTST stock system fit on an R?

Anyone got a stock R system lying around?

BTW: Sounds sucky with a cat. I know what will be going back on when the test is passed. Can't take away Godzilla's fire breathing ability :(

Don't think I just smart ass, but wouldn't it be better sense to make your own and keep it. If you have been pinged for noise once and you plan on going back to original after testing, surely you can see the possibility of getting done again. So! it would make sense to have your own spare stock system hanging around.

My system finished will be 3.5 inch from wategate entry back. 3 inch dump, 1.75 from ext wastegate, then 3.5 all the way including the cat. I'm sure I won't pass noise levels with this, so I will have a 2.75 press bent system on hand for just these occassions.

Yah thats cool i know what you mean but honestly 90% of the GTRs i have seen in vic have come of the boat with a aftermarket exhuast...and most people keep it on as long as they can if they get EPA'd then they will look for a stock one. OH well i'm sure it will get sorted out soon.

Also just wondering why would a importer import a container or stock exhaust they make the money with aftermarket parts thats why its sometimes hard to track them down..and with the new importing scheme less stock parts are avaliable. My 2 Cents :)

On the strength of the imports having a/mkt systems, maybe the go would be to strangle the sh1t out of the system at the end.

make up a bolt on for the rear muffler.

Drop the big 4/5 inch canon and put on a restrictive stock muffler, just for testing.

Let's be honwst, for testing nobody care about performance, just limit the noise.

Would be a lot easier than changing the whole system.

James, I understand you have a cat replacement pipe. Why not get another made with some mesh welded in and put steel wool in front of it. Will strangle hell out of it and make it quiet as hell but will be no fun to drive.

Do the testers check the system for cat etc?

Would even a basic restrictor such as this work? even out of just sheet metal.

You could just bolt in behind the cat, if it wasn't visible doubt they could tell, and it *should* quieten down the noise. Most silencers I have seen are little different that just reducing the diameter of the pipe.

Jamez..

i have the stock GTS-T system for rainy days :P and what i suggest is that you take your rear muffler out and have a pipe made up to fit the stock muffler to your existing system....

i kept my 3 1/2 inch system, simply took off the rear muffler, had an 'S' pipe made to fit the stock muffler to the 3 1/2 inch sytem, 100+ db reduced to 83db... :mad:

it takes two bolts to undo to replace the beast muffler back on...:(

and you are welcome to borrow my stock exhaust/muffler...

    • I believe @Duncan has given it a crack at Mt Buller before (in actual race conditions)
    • All my Polish car culture insight comes from watching Nightride. So I half expect this to get 1UZ swapped eventually?! Are you going to drive it in winter? I'm always curious how ATTESA would hold up in the snow. There isn't that much opportunity to try it in Australia.  
    • My steering lock unit on my Infiniti G37 has failed. The car is a local 2012 Infiniti G37 (Q60 ) I need to replace the unit My local mechanic said i need to buy a complete steering wheel assembly. Does anybody no any mechanics in Gold Coast or Brisbane who can fix this issue or where i can buy just the Steering lock control unit. Thanks
    • thanks, will conduct myself accordingly. i unfortunately put about 150 miles on the car before reading this thread again, however no PS issues, and definitely no turbo issues. it spools normally and still feels fast to me, probably because my previous car was an N/A auto sedan...gonna go fix the PS vacuum line though lol. safe to say, got what i came to this thread for. thanks  
    • Agreed, I've never seen a 260RS specific manual. As GTSBoy said it will mostly be stagea other than the engine loom https://www.hgeconsulting.com.au/stageaservicemanual.pdf
