I'm just going off what I've read - that all butterfly systems are illegal. Maybe it's only in some states. That said - if it were legal dB when fully-open, probably fine. I know some cars have these factory fitted - but obviously that's circumventing the issue.

A quick search picks up these threads discussing it. Mostly referring to Sydney, but yeah --

The last has an interesting comment - not sure how relevant in SA? I think EPA is national?

I'm not sure whether people are aware of this, but under part 19(1)(d) of the Protection of the Environment Operations (Noise Control) Regulation 2008 which commenced on 1 March 2008, it is illegal to have temporary noise reduction devices installed on vehicles. Part 19(2) provides 6 months grace, so this means that people can't be defected for noise control devices until 1 September. It is worth bearing in mind if you either have one of these exhausts fitted or are looking at fitting one in the future.

I thought it was to do with modifying the exhaust flow on-the-fly changes the emissions of the car? I could be off base though :whistling:

Interesting links there Jenna. And while noteworthy, I think an ECV is the LAST thing that most of us would get defected for :) .... but it would be interesting to see if you would or would not get through Regency with one fitted.

The apexi one is just a flange with butterfly valve in it yes? With a cable you run into the cabin? If so, as long as you hide the switch good enough, how would regency ever know it was there? Wouldn't it just look like any other flange in your exhaust?

looking for an r33 gtr pressure plate.. must have code 571 000 printed on it pm or txt 0401216575

I rang NPC and that number is a diaphram number and they need to know more specifics before they can match up a pressure plate

the bracket, and cable running off it going to the cabin somewhere would be a give away. As someone wise once said, they are assh*les, not idiots. From memory they even made someone weld in them silencer tips that you can remove to make it legal.

Looking for rubber pineapple mounts for the rear end of a r32. Got some metal drift ones in there that I'm really not Into lol. If some one wants them let me know. Also looking for the rubber strut tops for the front as one has completely deteriated. Cheers

^ NVM sorted

Considered one of those Dynomax VT mufflers? Unsure how well they work, would at least quieten it right down on idle.

    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go. 
    • More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).
