No one in the USA sells them either. I have heard of a few people who had them custom made including someone in your country.

EDIT: In case anyone is wondering, extractors are what we call headers.

yea ill do a bit more research here in Australia and ask around for more info and let you guys know what the outcome and price is...

Basically if you are after more power and better fuel economy, then you need a set of extractors. Basically extractors make it easier for the engine to push exhaust gases out of the cylinders. With your cars engine running more efficiently, you will notice improvements in fuel economy, and performance.
1. You'll get up to 15% better fuel economy.
2. You'll get increased performance.
3. You'll get more torque.
4. You'll get a cooler and cleaner running engine.
5. Your Auto transmission will run cooler.


cheers

yea basically what we need for a 4.7v8 is block huggers (stick very close to the block) due to engine bay restrictions...

I beleive that they would fit but extensive cutting of the body will be requiered, due to limited engine bay room...not worth it in my eyes

cheers
