My exhaust is a N1 Mega Premium.. Basically the best one I think.

The car has not been tuned correctly yet, do you feel this will help at all? Its been pre tuned but needs touch ups.

Thanks for all the feedback, It was actually vibrating the windows on my friends n13 and I felt bad when parents were looking at me with their baby in the back seat.. otherwise I wouldnt be so fussy

Yeah it's one of those things they often get wrong. You have to be insistent and make them read the law again.

I've often wondered if you could just go to a dyno and do something like knock 20 degrees out of your timing, take the dyno printout to the tester and say, "look, peak power at 3500rpm and only 85kw too. db test is at 3/4 of that. :( "

you may be onto something Adam!!! Wonder if its doable??? lol... Somehow I think they would tell us to get stuffed!!!

Either or if its factory specs then I win hands down.... Im assuming the factory specs on a RB25DET are around 5,000 to 5,500 rpm seeing as most are tested at 3,800..... If it was tested on real power then umm imine should be tested at 6,150 :P ... Id epic fail for sure!!!! lol

Perhaps DECIM8 can test your dyno sheet theory out!!

Yes your right I believe from what someone mentioned to me its higher like 93db not much really.. note ive got no 100% answer wtf it is so dont go on my word but I know its higher than ours/mine

Just to bring back a old thread, Recived a letter today from DECC or the EPA because my exhaust is too loud. The public can supposedly submit a complaint for such a thing.

Figured im going to a straight through muffler, for time being silencer is now in .. perm.

Warning for you all .. watch out :huh:

    • Update: I got the magnet out. I bought 3 different flexible magnetic reach tools, but none of them worked. The magnet on the tip was all less than 2lbs of force, so i had to buy a special cylindrical magnet that had a pull force of 9lbs.  The magnet finally came in the mail yesterday, so i got under the car to get to work. The super strong magnet isn't that long, so i only have about 1 finger pinch lengths to hold it. I was so scared when i was going in the hole, that the 9lb magnet would just fly away inside the oil pan never to be seen again, but i had my butt cheeks clenched and finger gripped on that thing so tight, i managed to get it to suck the other magnet out.  It was a victory for me last night.         
    • Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!
    • Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.
    • Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 馃槂
    • You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.
