Gu extractors

Hi Molopaa,

They are also known as exhaust "headers"

Extractors (also known as headers) are a replacement for the standard engine exhaust manifold. They create are a better and more even airflow drawing the exhaust gases from the motor hence the term extractor. A mechanic will explain it better but that's it in nutshell.

In most cases, petrol and diesel, they can increase power and engine will run smoother. Some say an increase in fuel economy as well but in my experience, just the same.

I had extractors fitted to a Mid wheel base petrol cruiser, FJ75 I think, with a petrol 4.0lt 2F motor. I also put on a 2 and a half inch exhaust with turbo muffler. What a difference. The most noticable change was how queit the engine idled but it also cruised a hell of a lot better.

Best money I ever spent on that car...
