These extractors where professionally fabricated to fit an LS1 5.7 litre Holden motor which was planted in a 81 FJ40 Toyota Landcruiser. While they performed perfectly. Once I changed the sump to one that had the drop at the back, instead of the front (to suit the front diff clearance) it changed the oil filter location. The oil filter ended up being close to the exractors. So a new set had to be made. That's the reason for sale. Diameter is 41mm.
Not that the following comment will reflect the sale price. But i paid $1800 to get these headers made up.
I will be putting more detailed pictures up shortly.

No.
You mean, are they tuned lengths? I had this debate with the fabricator. He's made headers for Ozzy V8 super cars. He made the replacement headers now on my 40. I asked for pipes to be tuned lengths. He was adamant that different lengths made little to no difference to performance at all. (I must say. I was skeptic at first. But this guy knows his stuff. They perform better than the last set of headers I'm selling, no question) You can talk to him yourself if you disagree. His name is Hayden. He works at Thorpe Engineering in Christchurch. Their number is 03-3485725.
hey, I've always had the train of thought, tuned lengths are the shit. Really. But Hayden changed my mind. But I don't expect to change anyone elses mind.

So.... When are you gunna get another 40 skid? Repower it with that ford ya talkin about n i'll throw in the headers for nothing. That's if you come down to Chch with it.
Oh well. I'm looking forward to using these Di-Filipo ones on the new LS2 in the Holden. I had them HPC coated inside n out. It's a heat resistant coating. Aparrently they don't dis colour like the chrome ones do and increase the airflow on the inside.
what diameter are standard headers?
