Exhaust To Pass Emissions

Hey guys,

Unfortunatley was out with a mate tonight and got defected at Penrith. Cops are everywhere out that way, and they have a full RTA inspection setup.

Now issue is that he read 104 DB and the legal limit is 90. What we need is an exhaust to borrow to pass. We're happy to pickup/drop off and also swing some cash your way. If not, anybody know how we can make it legal easily and cheaply?

Car has -5's and 2.8 stroker etc etc.

Also he got defected on height and he has stock shocks/springs. Is there any adjustment from stock?

Thanks,

Aaron

If the car is too low with stock suspension, then it is either stuffed (sagged old springs) or someone has done something really dodgy. The other alternative is that the car is not actually too low, and the cop is a dickhead and has just written the defect up hoping that other things will turn up at inspection. The other alternative is that the car has a stupid body kit or low hanging exhaust. That would be deserving of the defect.

If you want a cheat for the exhaust, make a plat to go between flanges that has a number of 10mm holes drilled in it. The more holes, the more noise and the more gas will pass through. Too few holes will choke the motor so you can't drive it. You do the work/math to determine what you need to get it mobile and passable.

Just went through this 2 weeks ago.

Be aware that they will not only test your exhaust DB reading, but also pop the bonnet and sus out things like atmo bov, uncovered air filter(heat sheild is not legal), atmo catch can etc etc that they will fail you on.

They also put the car up on the hoist and go over the exhaust system to see if its been tampered with. Its all documented and pics are taken.

They will note that exhaust bolts and been recently un-done/done up from fresh marks, dirty hand prints showing its been 'tampered' with. The guy in Granville was pedantic with it all and reasonably cluey. You can't pay extra to 'just pass it', its not like the dodgy pinks and blues people get.

Rumor has it, the guy in campbelltown is more 'forgiving.' So will try him next time.

However, even that he knew it was tampered with, at the time he did the test, the exhaust was under the limit and nothing caught his eye that was illegal so he passed it, but again took pics of everything.

oh and the plate with holes in it, between a flange works a treat. Just be sure to make it looks as close as you can to a gasket.

Lucky i didn't fit one then lol, I was thinking of mounting one between cat and rear muffler as they sound a bit hissy on the rear, I guess i thought maybe the cops wouldn't defect it if it wasn't noisy and then not have to go through all the hassle, but I figured they would be onto it in the end!

That clown in Granville Failed my exhaust becasue the silencer was not welded in, Therefore not part of the exhaust and a hazard.

Had to pay for that, then come back again after a shitty weld job and back to get tested again,

He didnet check anything for tampering, I had the flanged closed ect ect

Far out Sydney has gotten bad. Can't even drive your car around down there anymore.

Gotta be stressing to drive anywhere near Sydney now. We don't have these issues on the coast..... Yet!!

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
