OK - so if I had read 91dB, I would have been cross, so to prepare, I fitted a CAT (thanks Gerald) and prayed to JASMA hoping for a legal pass...

97.8dB @ 5400 rpm!

Worth doing, worth doing properly :)

I think that's something like 6x louder than it should be?

The tester liked my titanium system, didn't charge me for the test - and said come back with a stock system for a big tick.

So... does a GTST stock system fit on an R?

Anyone got a stock R system lying around?

BTW: Sounds sucky with a cat. I know what will be going back on when the test is passed. Can't take away Godzilla's fire breathing ability :(

Don't think I just smart ass, but wouldn't it be better sense to make your own and keep it. If you have been pinged for noise once and you plan on going back to original after testing, surely you can see the possibility of getting done again. So! it would make sense to have your own spare stock system hanging around.

My system finished will be 3.5 inch from wategate entry back. 3 inch dump, 1.75 from ext wastegate, then 3.5 all the way including the cat. I'm sure I won't pass noise levels with this, so I will have a 2.75 press bent system on hand for just these occassions.

Yah thats cool i know what you mean but honestly 90% of the GTRs i have seen in vic have come of the boat with a aftermarket exhuast...and most people keep it on as long as they can if they get EPA'd then they will look for a stock one. OH well i'm sure it will get sorted out soon.

Also just wondering why would a importer import a container or stock exhaust they make the money with aftermarket parts thats why its sometimes hard to track them down..and with the new importing scheme less stock parts are avaliable. My 2 Cents :)

On the strength of the imports having a/mkt systems, maybe the go would be to strangle the sh1t out of the system at the end.

make up a bolt on for the rear muffler.

Drop the big 4/5 inch canon and put on a restrictive stock muffler, just for testing.

Let's be honwst, for testing nobody care about performance, just limit the noise.

Would be a lot easier than changing the whole system.

James, I understand you have a cat replacement pipe. Why not get another made with some mesh welded in and put steel wool in front of it. Will strangle hell out of it and make it quiet as hell but will be no fun to drive.

Do the testers check the system for cat etc?

Would even a basic restrictor such as this work? even out of just sheet metal.

You could just bolt in behind the cat, if it wasn't visible doubt they could tell, and it *should* quieten down the noise. Most silencers I have seen are little different that just reducing the diameter of the pipe.

Jamez..

i have the stock GTS-T system for rainy days :P and what i suggest is that you take your rear muffler out and have a pipe made up to fit the stock muffler to your existing system....

i kept my 3 1/2 inch system, simply took off the rear muffler, had an 'S' pipe made to fit the stock muffler to the 3 1/2 inch sytem, 100+ db reduced to 83db... :mad:

it takes two bolts to undo to replace the beast muffler back on...:(

and you are welcome to borrow my stock exhaust/muffler...

      They are in fact just nozzles. They are there only to produce a spray pattern and limit flow. The injector itself is what I use to control flow to the 7x nozzles. My old system had no injector and only PWM the pump. This lead to a lot of inconsistencies, and poor atomization at low pressure when the pump was ramping up.

      With the system, once you drive it for a bit, and before you turn the car off, does the car fix its date and time? When you say the date is wrong, what date does the vehicle think it is, and does it always show the same date? My thoughts from a process driven view is; The system may be defaulting to a standard start date/time. The main reason you'd typically see this occuring, is the system is losing its constant/backup power supply.   If its always defaulting to the same date/time at start up, and especially if it fixes itself while driving, I'd say either the non volatile memory has an issue, or the power supply to the volatile memory that stores this information.   The other thing I'd check is if there is anywhere in the system you can adjust the date and time from. If the date/time is still moving forward since it wished you happy new year, then it is 100% possible the system has just had a bit of data corruption occur, and you likely need to find a way to reset the date/time in the vehicle.

      Jacks that fit under GTR lips that can reach the subframe?

      Scissor Jacks are an accident waiting to happen, the only time they should be used are in an roadside flat, even then a tyre and rim should be placed underneath
