Hi everyone. My IIA needs a new exhaust, and I'd like to fit extractors at the same time. What are my options?

I have seen a set made by Genie, but do other brands also make them? Which is the best and why?

Thanks :)

once upon a time Perry were the only ones who made them, so you could contact HM Headers (Perry Exhausts are now a part of HM) if they still have the jigs and can do it.
They definitely work. Back in the late seventies, my uncle had a Series III with Perry headers, a 2" exhaust and a couple of carby tweaks and the thing would do over 140km/h with a Fairey O/D ! :eek: (Dear old Dad can back this up. Uncle David is sadly no longer with us)

Interesting, thanks for the info. I can easily believe that they work, the stock manifold looks terrible!

So, are any other members using extractors on their 2.25 petrol?

OK, thanks for that. I waited, hoping he would reply in here...

Do you know the brand? Price? Availability?

I've got extractors on a 2.25. They came off a wreck that was part of a deceased estate, so I don't know who made them. They leaked and I had to get them cut down so that the flange was near the join of the pipes - that meant that the cracks at the join could be welded from the inside. Anyway, they work pretty well.

But the biggest improvement to performance I found was to have the cam ground. It only cost about $110 and the lobes were ground to specs similar to the 6cyl cam. That meant that all the valves (inlet & exhaust) opened 5 degrees sooner and closed 5 degrees later. This allowed the engine to breathe a whole lot better.

I had extractors on my 2.25P and now on my 2.25D. the 2.25 came with extractors, and when I built the 2.25D I bought extractors (Lukey I think). They weren't very expensive, but I can't remember how much exactly.

Ahh right. Are diesel extractors the same as for the petrol?

It's been a while - but I am pretty sure the ports are in axactly the same place, but the stud pattern is different. So NO.

I have had a set of Lukey Performance Headers (LPH 620) on mine for a while and I am very happy with them. If I remember correctly, I got them from Toms Tyres and Mufflers here in Darwin. ;)

Interesting, thanks for that. I went to Mountain Mufflers today, and they went through Pacemaker, Hurricane, and Genie, with no luck. They said they can make a custom set for $800.... only about twice the amount I am willing to hand over! I will try to contact Lukey tomorrow, thanks!

I seem to recall my Lukey extractors for the 2.25D were $140 (but I think this was a cheap price as they had ordered them for someone else who hadn't picked them up). I sold my 2nd hand 2.25P extractors to a mate for $70.

That would be about right. I can recall paying about that much but cant be sure - I was impressed at how cheap they were.

A bit of mild exhumation here, I am going to be looking into getting some extractors for a 2.25 petrol pretty soon. Does anybody know the best place to get some (new or used, as long as they work). I did a little bit of a call around and they all seemed pretty vague. Any help appreciated.

I suspect many companies have stopped making them. Best bet would be to contact all the manufacturers directly (walker, genie, lukey etc...) and ask if they still make them. Some large exhaust places may have old stock.
