OK in the past 2 weeks ive been defected 2 times.First time was for blow off valve.

Second time was for exhaust and my HIDS.

The first copper said my exhaust was fine but not to go any louder.

The second copper was a prick and wrote me up anyway.Today i went to get it tested and i was 4DB over(shit) so i went and got a standard exhaust put on.But the thing is i have to give it back in two weeks(loaner)

Seeing as my other exhaust was only 4DB over what can i do to it to make it quieter without comprimising flow.The standard system has robbed so much power out of my car its not funny.Can anyone in the same boat help me out?Options? Is there quiet high flowing systems on the market?

CHEERS

I guess ill have to try the centre muffler option.Going from high flowing to standard exhaust is a huge decrease in power.Amazing what a high flowing exhaust can do for turbo cars.

yea bud the best option is to get another centre muiffler as the others on here have said... the hks super dragger exhaust i have has a centre muffler and a hotdog aswell... its pretty quiet so that should do the trick for ya

My one is a fujitsubo.the guy testing it was suprised that it was over cause its pretty quiet.The standard one i have on now is 88.5db. My aim is to find a system that is 90db but provides the same flow as my fujitsubo one.There must be a market out there for legal yet high flowing exhausts.

Now on the subject of defects.I have an intercooler in the garage ready to put on.Are they a defect.A hole has to be cut into the engine bay to fit it.

If you're cutting a hole in the engine bay you're going to have to get that engineered, otherwise = defect?

(Going by what happened to a friend of mine)

Go to Mr. Muffler - get a Muffler that's within the legal DB limit - get the guys to write you up a report stating that it's legal - make a copy of it and keep it in your car...

When a copper pulls you over - show them the paperwork and that will shut him up.

That's what I've found...

Simple get an exhaust that complies.

There are some made by kakimoto and fujitsobo that are legal.

they have a 92 or 96 suffix on the model names.

can't just get an exhaust that applies, it needs to be engineered to say that it comply's with the australian design rules.. i was defected for my exhaust, and mind you my exhaust is under the dB rating.. i was told that if i didn't have a engineered certificate to say that it complys with the australian design rule then they can keep defecting me..

simple answer: Either know someone dodgey to clear it like i did... or put the stock one back on.

This is true. Although, if you are defected for noise - my solution would suffice.

If you are defected for no ADR compliance - your solution would be the only one.

      Quieter performance exhausts (or muffler add-on options)

      By Murray_Calavera · Posted

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
