put my stock cat and factory cat back on and went to campbelltown on tuesday to clear my exhaust, i failed as it registered 96db...with the stock exhaust !!!

dunno how this can be but im about to take the exhaust to a shop to get a big muffler put in

The ADM R32 GT-R's got a different rear muffler for exactly that reason. I thought it was a bit strange and to be honest I can't pick the difference between my ADM or JDM ........ they sound the same to me.

Yeh

At the defect area the EPA were there Testing exhausts for noise with mic's

And snooping under the bonnet to make sure all the charcoal canisters are connected, no bovs or atmo catch cans, etc etc

Also checking window tint, thankgod mine is 35% and all the other usual crap

One guy asked if I had my bucket seats engineered, told him to check the other gtr over there cos they are factory !

As for loud exhausts, to flow huge power and be quiet it's going to need to be a custom job. Custom = expensive, which is why hardly anyone goes down that path.

custom isn't necessarily expensive. It depends on if you let someone rip you a new one, or go quality. My system fully fitted cost me less than it should have, but turbo back, custom built mufflers, and a new metal cat should have cost me $1500. I don't think that's overly expensive. Yes more then a "I'll take a noisy ass 3" for $300 thanks!"

Anyone who heard my old 2530 can attest to the fact that it was very quiet for what was in front of it. A verydeep but not loud note at idle and as it came past 3000rpm you could hear the motor louder then the exhaust... Rare in a turbo car.

Ill say one thing it's the drivers fault. The car mods have nothing to do with it. It's just plain stupid, this has to stop who ever rights the rules is a complete idiot with no brains. A Speeding driver is a speeding driver. There gonna speed in any car, and they should not be tighting up any engineering rules if a engineer says its safe to be on the road so be it.

upto the cop that decides to pulls you over.......if they want to defect you they will and they will do it however they like....

in my case the cop full lied about what was on my car and i only found that out once i obtained the details from the SDRO (ie the actuall hand written report from himself) and fined me for not meeting as per the engineers report etc etc

the story goes on but gives you an idea.

    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
    • I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things
    • I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt 
    • So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm. 
    • Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
