Don't bother with them. I noticed a huge improvement when I changed my Lukies over to Pacey Comps. If you can't afford the Pacey Comps rather keep saving, but don't stoop down to the Lukies... DOn;t get me wrong, there better than stock, and there not expensive, so good bang for you buck, but if your gunna change em over, do it properly.

well i dunno about about pacey headers .but comparing my engine to other au 's with simalar mods .mine makes its peek hp at 5400rpm were as others run out of puff at 5000 to 5200 rpm .the only difference is i run a lukey sytem .
i'd love to see someone do a dyno shoot out with all the different brand of headers on the one car.

making power at 5,400 is absolutely useless for a road car falcon! I mean you'd have to be doing 80km/h in first gear to get in the power range! And so wouldn't improve your economy at crusing much either!

So your telling me that the Lukey extractors produce a power band from 2400 to 5400? That's is bloody long, 3000rpm. I didn't think the stock cam shaft was ground to produce peak power as high as 5400.
Sounds like crap to me considering I used to have them on my EF. The Lukeys have got no wear near the power increase the Pacey Comps have below 3500. I noticed a big difference when I changed over with my stock cam, and even more when I fitted the wade!

Then there's that kick in the back from about 3850 (when the BBM switches) theintake flowing better, the pacies evacuate the cylinders beautifully. It's all good.

my car isn't stock .it runs a jmm sreetfigher cam kit and compared to other guys running them ,mine makes a little more power at a higher rpm .the only difference is i run lukey headers

i didn't say lukey's were better than pacey's as i have never used them.i was just letting ef mont ghia know about my how the au goes with lukey's and they would be worth having a look at.

There is a trade off with extractors - the exhaust note sounds better so you drive to hear the new note - and use more petrol.
The other problem can be higher engine compartment temperatures.
This can affect your starter motor performance.
