Difference between Headers & Extractors...

[Dan355]

Nah mate. Extractors and headers are the exact same thing, its just they have always been called extractors here for decades, headers always in the US.

I initially thought that to. As discussed in the other thread. I thought tuned length were "headers" and the other "extractors". Who knows>? Im still getting told both stories.

what about exhaust pulses??? extractors do just that .. extract the exhaust gases.

tuned length extractors are exactly the right length and collect in the right spot to optimise exhaust flow out of the enigne..

tuned length headers are good for tuning the power band, unfortunatly equel lenght tuned headers tune over a norrow rpm band. unequal lenth headers don't tune as well but do it over a greater rpm range(this is for V8's only as far as i know as it has to do with firing order/exhaust pulses down the headers etc and it's different for V6/inline 6/inline 4's etc). as far as i am aware equal length tuned headers are over rated. but yeah, headers/extractors, same thing

Hey guys,

Just a quick one, what is the difference between Headers and Extractors?? Ive heard ppl talking about both but never knew the difference....any help apriciated

Cheers

is your name really francis?

Tube headers/extractors are generally made from stainless steel piping, whereis stock manifolds are made of cast iron.

This is possible at only one RPM though.

There are both tuned length headers and tuned length extractors... Because headers and extractors are the exact same...

Only HM seem to be the only real tuned length header going around, however Pacemaker etc. also claim to be tuned length extractors.

its exactly the same as a supercharger and a blower. ones old school and the other's 'new age'. but one always sounds tuffer. blower and headers go hand in hand, just like supercharger and extractors (sounds more technical)

 

[craigvk]

I prefer old school personally. Too many young punks talk too much trash. It's like when people say 'worked' or 'modified' engine. Same damn thing.

Its not old school though. My pop called them extractors when he was my age 45 years ago....

Its just a difference between Australian lingo and American lingo.
