www.wikipedia.com or top right hand corner search , there are plenty of threads about extractors if you look

i got mine put on this week. bit better acceleration, revs up faster. more pull from lower revs, eg doesn't bog down like it would going up hills, etc. already had a catback.

You'll get a lot more midrange with them, and maybe pick up 3-5kw in the top end.

cheers guys where abouts could i find them i looked on ebay and i cant find any in australia. if i find some for an rb25det will they still fit my de?

In Australia, it's either custom made, or get them from DKNE (Dumper King n Exhaust).

Unless you're willing to import them and get the tried & tested Coby Extractors from Parts Co in New Zealand.

Good idea to get them HPC Coated also and shield them from your air box...I forget who it was on here who had extractors melt through the airbox.

With DKNE you can pay for the optional Flange to be able to simply bolt on without welding.

RB25DET doesn't use extractors. On the N/A RB's the extractors dump to a front pipe, to the cat and then the catback. On Turbo RB's the turbo manifold replaces the extractors and the exhaust gas drives the turbo charger exhausting out the back of the turbo through the dump and front pipe to cat to catback. Very different concept.

i have a set up for sale at the moment mate. when i had them on my 25DE they made a noticable difference, especially in responsiveness and high end power, really opened things up...they were on an R33 but im pretty sure they bolt straight up to 34s aswell. make sure you have a catback to go on down the track too. that combination never fails to work wonders

mine are cobys, all flanges are on and ready to bolt on.

$250 and theyre yours.

Put them on my Supra and I honestly didn't feel any difference. Apparently they're good for 15-20rwkw on the 2JZ-GE (not JUST the extractors, this is stock exhaust to full custom exhaust), but I like I said I didn't notice it.

Once I replaced the exposed pod (this is after the exhaust) with a stock box and aftermarket panel filter I did notice a significant boost to power, although nothing spectacular.

Point I'm trying to make is unless you're planning on taking your car to the track, drag strip, etc and really want to squeeze every watt of power out of it, I suggest you don't do it. It's expensive for very little gain. Put your money towards cosmetics or save it for when you get off your P's.

Although one great thing about the extractors (at least on the 2JZ) is it makes the exhaust note sound awesome. Very high-pitched, racey and unlike 90% of the deep and "droney" import cannons out there.

it made mine quieter on idle, and a lower tougher note on WOT higher in the rev range
