Cheap ebay 'Empire Performance' extractors anyone?

my experience with ebay extractors is pipe thickness is not enough and they are almost never flat.

What do you mean by 'flat' How can a header be 'flat' :?:

It has 2 flanges, both of which need to be flat, the head flange is warped often.

Yeah, I could see how that would be a bitch.
I would give them a try, price is right, but the gain on a NB8B would be insignificant.

Could you measure the outer and inner diameters of the runners just for comparisons sake?

My set also turned up yesterday. I have not had a good look at it yet but I was pleased to see they supplied 2 gaskets and bolts which was not mentioned on the ebay listing.

Looking at the position on the o2 sensor I am presuming I will need to lengthen the o2 sensor wire.

Yes you will need to lengthen as the o2 bung seems to be further down. I was going to replace mine anyway as i am unsure if it has ever been done.

Put a set of these on over the weekend just to try them out.
No noticeable change except for a little more volume above 4000rpm.
I'll see what happens when my cat and exhaust arrive.

Flanges were fine. Checked them with the straight edge before install... all good.
6 days in and no issues.

200 dollars for 'no noticeable change'..?

I had a cracked weld on the old rusted unit, so figured $169 wasn't too bad as I plan to turbo down the track and it will have a short life in the car.
I wasn't expecting anything impressive at that price point. :wink:

Mind you, I've only dríven it to work a couple times. Which is literally 3 blocks away.
I'll take it out on the weekend and give it a real trial.
