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.

      Unpeeling the Orange

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
