True extractors are pipes which are the same length from the exhaust port that meet together at a collector.
Headers are like extractors (made from pipes) except the pipes aren't the same length and usually join to each other before reaching a collector.

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
