of course that's true, and it's a risk! But the emission standard that car manufacteres need to meet for new factory cars are higher than the on road requirements of a car.

anyway, the fine for having no cat is hefty your right... lucky i have two cats.

Thats good that you notice improvement, Though im selling the car in a years time im going to avoid putting on an exhaust.

What I would like to know is what is the stock fwkw and power/torque curves compared to with having an exhaust done.

haha, sounds sweet at high revs,

good thing is that you can close it off....

If you want power gain, you need to do more than the exhaust, because there are a few pretty damn restrictive parts on the aurion...

if you guys want more details, and anyone in melb wants to know the best deal to get it done, just pm me!

Also remember you might be just shifting the power curve steeper, i would advise anyone who is looking at improving their 'day2day usable' power to get it dynoed first and get recommendations from that. Otherwise you'll be revving higher on 6th gear to maintain speed on a freeway cruise cause your lowband has been sacrificed.

When you're tested for emissions, you're compared to the ADR at the time your car was manufactured ... there's no difference between "factory cars" and "on-road requirements".

If you meet those requirements as-is, then good for you. But if you read too high, and they realise you have fewer cat's than the standard car, then I think they'll come down hard.

At the end of the day, its like breaking any law deliberately ... if you've made the decision to do it, then you can't whinge when you come unstuck! :-)

Are you referring to this piece of design excellence:

If so, I don't think anyone has yet eh. I'm thinking, it probably wouldn't be worth all the effort unless you have a complete system done for it (eg. dual pipes to the rear).

Yep that one, I figured as much.

Im looking around at the moment to see if the Lexus GS range has cat backs or anything else similar that we can bolt on with slight changes. So far though all I have found seem to be leaning to the right side more due to being RWD.

Ill keep looking.

      Disconnecting winch, lightbar and UHF

      Generally, yes. In the 60s, and earlier, there were cars with positive grounds, so I'm always a bit hesitant to say the negative wire. It is always the one that bolts to the body. Herb

      2011 Land Cruiser 1VD-FTV Engine Won't Start After Overhaul

      Hi everyone, I have a 2011 Land Cruiser VDJ200 with a 1VD-FTV engine. I recently had the engine fully overhauled due to a blown head gasket. However, after the overhaul, the engine is not starting. It only cranks but doesn't fire. I've checked the following DTC codes: Internal memory EEPROM error Low rail pressure The actual rail pressure data shows: 240 bar during cranking 61 bar when ignition is off Based on these findings, I suspect the following potential causes: =Defective Diesel High-Pressure Pump =Leaking Piezoelectric Injectors =Diesel Fuel Bypassing to the DPF Circuit =Faulty Injector Drivers I'm hoping for some expert advice to help diagnose and resolve this problem I'm seeking expert advice on how to troubleshoot and resolve this issue. Any suggestions or guidance would be greatly appreciated.

      Disconnecting winch, lightbar and UHF

      Disconnecting batteries, ALWAYS disconnect the ground wire first. Doing this will also disconnect power, in general. Herb

      Disconnecting winch, lightbar and UHF

      Hey guys, I’m wanting to disconnect my current winch, lightbar and UHF as I have new plans. I’ve installed a winch previously on another car so I get it’s a case of following the cables and disconnecting from the battery, etc but but safety wise, should I start by disconnecting the battery so the cables aren’t live orrrr? And if so how do it go this haha?

      Snapping wheel and axle studs

      Put a set of standard wheels on it and your problem will disappear. It is critical that the hole in the wheel centre is a snug fit on the axle boss (without wheel nuts fitted). If your wheels are sloppy on the axle boss this allows excess force on your wheel studs and they will break, as yours are doing. If you are unsure of what to do, go to a reputable tyre shop and get assistance.

      2zz idle / roughness when accelerating past 3k

      Hey everyone was hoping someone might be able to point me in the right direction with this issue I've been facing for a while now. My Celica's idle will drop down to almost 200rpm when stationery after hitting operating temperature. Pretty much feels like it's about to stall out but never actually does. When taking off from a set of lights it almost feels like it hesitates or is down on power and then all of a sudden it lurches forward and gets a boost in power again. Then again around 1,500-3,000rpm it feels down on power and in what I can only describe in the engine feeling scratchy. Past 3,000 rpm it gets a little boost in power again but still definitely feels down on power compared to what it used to be and still has that roughness. Note lift is also not working at the moment but I have changed the lift bolts, planning on cleaning the VVT and VVTL-i OCV's New engine mounts have been installed I changed the MAF sensor about 4 years ago albeit not OEM. After doing some research my main ideas now would be a New MAF this time OEM, TPS, IACV or Coil Packs (Changed plugs 50,000km ago) Any other suggestions would be greatly appreciated!!! :)
