Hey Everyone,

So, i got pulled over for RBT last night and most times i'll be right to go without any troubles but not until last night from all the f....... coppers. They gave me a notice to get my car tested at EPA (Dc something rather) in NSW.

I have a turbo back exhaust with a 3" high flow cat and 2.5 or 3 inch muffler and fitted on my silencer today. The noise in car has dropped dramatically but not too sure if its still too loud to pass the test. Has anyone experienced this and know if the silencer does help with the noise reduction?

Also a tip, should i remove my electronic boost controller in my car to avoid more defects when i get tested? LOL

On my notice, the police only stated excessive noise, so will the EPA only test the exhaust only?

Sorry for so many questions guys, im just curious and see what should i do to prevent spending more money to purchase all my stock parts back and refit them again.

Thanks

Henry

The EPA tester only tests the exhaust, he dosen't care abour mods, as long as the car is under the limit (in vic its 40dB)
So yeh, he places a microphone about half a meter away from the exhaust and accelerates to about 5K(for me at least), that's it. It takes about 5 minutes, it's a shame they charge you $41 for it :(

Hi Mate,

Thanks for sharing. Yes i have heard about the flange/gasket trick but i have a full turbo back exhaust with a massive muffler, so when i do that trick and have it inspected the EPA is not stupid and think that my exhaust could pass that easily. Thats what im worried about at the moment. Bloody cops man pain in the ass! I've own my car for 5 years and this is my 1st time i've got done for my exhaust =(

90dB in Vic as stated above. EPA may check your emmissions aswell so make sure your cat is up to scratch. They usually hold the revs at the revs that they reckon the car makes peak power at and measure that. I had an RB20 and they held it at 4200rpm. I didnt argue. The car was nice and quiet at those revs and passed no problems.

Haha, no they're not stupid, but its not their business to check how its legal, as long as it is.

to put it into perspective, my gasket(metal plate) was flimsy and when you accelerated above 3K you could hear air escaping like no tomorrow, but the tester didn't say anything!

And i'm sorry, my mistake, the legal limit in vic is 90dB, not too sure why i typed 40 haha

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
