pics of extractors

[Driver]

hey,

just out of curiousity

does anyone have any pics of the stock extractors for r33?

I wana see the difference.

[NA_R33]

i dont have pics but basically the stock manifold is a 6 into one unit and looks really ugly, whereas the actualy extractors, have the same length pipe coming out of each exaust outlet, then each set of 3 (front and back) into 2 pipes and then finally flanged into 1.

i thought the stock ones when from 6->2->1 formation.

regardless of what it is, how much do they weight out of curiosity

i have my old ones sitting in my garage, i'll take some pics on the weekend if you want. compared to the coby extractors i have (8kg) just going by feel the stock ones would be at least twice as heavy, if not more.

[Driver]

if u could that would be great

im gona put the new 1's in myself, later on in the yr when i get em..

[Driver]

whats rough price on how much its gona cost me to replace extractors upto the cat?

[nismoman18]

my stock ones are 6-2-1. final outlet is 2 1/2 ? does this sound right! or do i have aftermarkets already. u guys were saying the cobe extractors were only 2 inch out! means smaller then stock or what ?

[NA_R33]

sorry, stocko's r 6-2-1 my mistake, and yes they are really heavy, as for the final size im not really sure sorry.

greg ur stocko's were completely different to mine, wierd....

[Driver]

thanx for the pics

from what i can see on mine - they look pretty similar to that..

[Greg]

john is your r33 "Type S"?? the Type S had 5kw more power so maybe this was gained from different extractors, although i read something somewhere about variable cam timing giving the difference in power so i'm probably wrong.

[nismoman18]

the stock ones look bigger then the coby ones ??? hmmmm u sure they arent made specialyl for RB20's

[Greg]

they are made for both RB20 and RB25, so its a bit of a compromise. i probably lost a bit of top end power but the low end torque more than made up for it. i'll measure later to confirm

I was just lookn up info about extractors then

[SillyFlyFresh]

as i still havent bought a set yet

just want to know your verdict if i should get some

[Nismodified]

holy cow those stock extractors look scary O_O

[Greg]

SillyFryFresh,

I am really happy with the extractors. They give it heaps more go at low revs and make it more fun to drive around town normally. Fuel economy is improved as well. I've gone from getting about 11L/100km to about 10.2L/100km (that's being pretty hard on the car, lots of start stop traffic). You get a nice deep rumble to the exhaust as well.

My only gripe is the heat they create. If you get them, before you have them fitted, remove the paint and then wrap them in some exhaust wrap, because its bloody hard to do it once they're on the car. I'm looking at making a custom heat shield for the extractors and wrapping my intake pipe in some cool tape instead of this.

Hope this helps
