And if you have to do a db test they will probably tell you to change as its not allowed to be adjustable, does not matter what the engineer has signed off on.

Cant. As long as they dont hear it they have nothing to stand on. Especially when the controller cant be found :-)

Also should add i also have a cat. a highflow shit one that probably does less than nothing.

The EPA down here are not idiots.

They are well aware of Varex mufflers. If you have one, you fail.

1.buy varex

2.get old rusty muffler from exhaust shop

3.put rusty case over varex

4. Profit??

I have no interest in dodging any thing up, I want it 100% legal so I don't have to worry about it if I have to get it tested.

16-18" x 12" x 8" rear muffler

that will get your 3" exhaust legal easily if you have a decent middle muffler.

I didn't miss your post titan, I will measure the ones that are in there and see if there the same size, put on hold for now tho as I think I f**ked my clutch on the weekend so I have to pull the box out and see what the problem is, atm I just wanna burn the f**ker!

Welcome to nissan ownership.

I've had it for five years now, lately tho 5 things have f**ked up one after the other, most minor but the most it has been running fine for in between each is 1 week, now I have to pull the box out again to check my new clutch

the biggest issue is getting it quiet at idle/low revs with big pipes, easier with 3" than 3.5" or 4" as there isnt enough exhaust gas flowing through to make the mufflers work their best

you can stick huge mufflers in it like i/you have done (mine is 4" -> 3.5") and you are fine at revs, but dont pass the idle test (which isnt applicable in the ACT (or NSW afaik) but is part of the VIC test) as that is the part of the test i assume you are failing on? or are you failing at revs?

No idle test, it has to be 90db or lower at 4800rpm, no other tests for noise are done.

Doesnt matter, maybe in vic its different but. In NSW, my engineer said its tested shut, driven shut, there is nothing they can say. Even if they know its a varex. He said there is no difference in me testing it with that or having a quiet pipe then swapping it at home. Except how fast it can be done. He instructed me when harassed about it to take it to the top as he told others who succeeded.

Thats NSW laws though they smash you's alot harder there.

what about adjusting the idle speed lower? would that help the idle test..

i have a 3 1/2inch system with restrictor in muffler but will put a 4inch nur spec muffler on soon, so ill be in the same boat, might be 100db so would 2 big 3 1/2 inch mufflers do the job?

hmm have to wait and see, i think in queensland this isnt so much a problem..

Who is your engineer in NSW? PM me if you don't want to post here. I have done the ring around and there's nobody I

found that would test a variable exhaust at anything other than fully open.

To the OP: it's super unlikely that you'll get done for 92dB vs 90dB. You can get that much variation from temperature and surroundings on the day (lower temp = louder; harder surroundings = louder). If you pass the d1ckhead test you could probably get away with 95dB :P Resist the temptation to tell Mr. Po Po to jam it, and you will avoid being in a world of hurt.

Cheers,

SW

    • After @Kinkstaah debacle, I'd never want to try and get it right 😛
    • The hood lines up with the fenders. The front bar doesn't perfectly line up with the fenders where the wheel arch is. You have to 'squeeze' the front bar 'in' as it wants to naturally flare out and be longer on the sides. There's a few threads where people notice this when they only swap a GTR style bumper and front bar. Unless you have genuine OEM items - you may be better served getting conversion kits. There are GTT bumpers to fit GTR hoods. There are GTR hoods (non genuine) to fit the GTT bracketry. MAY  
    • The real question is, on some of those wild roads they call highways, how many times did a farmer in an old ute from the early 2000s blaze past you over double lines?   Tassie is a wild and really cool place, and after doing a work related road trip there January of 24, I understand why Targa Tasmania is ran there, and is so tough to do well at! We had a brand new Camry Hybrid that handled quite nicely, and thankfully weren't in an old car, because cresting some of those hills in a 100kmh zone for it to suddenly be like "surprise f**kers, this is a recommended 30kmh hard right turn" wouldn't be pretty. We weren't racing the Camry around, but we weren't slouching in the bends either. But my lord those old farmers know their old clapped out utes, and those roads, as they were absolutely hammering it!   You're also super lucky to make it up to Mt Wellingtong this time of year. It's often road closed with snow/ice! Also, I hope you hit up Salamander Road in Hobart for some insanely good food (I highly recommend the dimly lit Irish pub for a Guiness Pie, or even the bangers and mash!!!)   How long did the Ferry take to get across? I want to do a road trip of Tas on my own time, but I get horrifically sea sick, and I don't want me on the Ferry, just the car 😛
    • So far so good, about 30km on it so far and nothing out of sorts yet thankfully
    • Look at @Kinkstaah's thread on the issue.
