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.

Where in Penrith was this?

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!!

    • Don't do it if your gearbox box has already having syncro issues. The short hifter will put a greater load on them. If you must I remember Nismo did a shorter shifter, with the top part being physically shorter and the part that went into the gearbox was the same as stock. In saying that I've had a C's short shifter (I think) in mine for many years, which was given to me as the previous owner was not sympathetic to the gearbox. Thus forwarned I was careful and had to modify my normal changing style. You have to be super accurate with your clutch and shifts
    • Well, after a week of daily driving and having to crawl out between the wheel and the side intrusion bars. I got myself a quick release setup. I went with an NRG short hub and Quick Release with some cute heart cutouts on the pull tabs. Nice and matchy matchy with the rest of the interior accents I have going on.  The only downside is the total stack height even with the short adapter is longer than the old HKB boss kit. Luckily I had some adjustment left on the column so move the wheel away.
    • stock shifter with new bushes, springs and cup will improve it. Gktech do all the bits. The opinion as the years have gone on is the redline is not great in old gearboxes.
    • Hi all   what short shifter do you use on your skykine r34?   my synchronous does have a problem and i was getting huge delay and grinding sound between 2nd and 3rd, did put shockproof red heavy stuff and it is great now/ no issues   would in your view short shifter screw this up?   people seems to suggest/ use cube short shifter and there is standard and premium. Seen review of premium as much better and less play. Thoughts?
    • Yeah, there's a bit of a density and friability difference between pebbles and any of those other things. Silicone will definitely float in oil and so will be mobile enough to move around. Although, again, if it is upstream of the filter it really shouldn't go any further. I would only ever worry about silicone when it is in places downstream of the filter. Upstream of the pickup is a whole 'nother matter. We've all seen what that does. I have seen the most abominable crap settled out in industrial gearboxes, trunnion lube systems and the like, without any sign that any of it has touched anything in the machine. Just chilling in the bottom, waiting for the inevitable operator error that causes the whole machine to need to be dismantled for repairs.
