Any brand of extractors can be HPC coated. I have a set of genies on my v8, and they are great quality, and easy to fit. Genie have had a good name for a long time, but sort of dissapeared a few years ago due to financial troubles.
i was talking to a guy at work who used to be a sales rep for genies, and he said they used to have certain v8 supercar teams etc there developing the extractors, so they must be of reasonable quality, they look good to me
Have you driven a Ford....lateley?
Advertising has come along way-----But still not far enough!!!!!

From what I have been told, Genies are actually really crap (sorry if this is depressing :() Because they simply allow SO MUCH exhaust too flow, the exhaust gas velocity is too low, and they don't scavenge the combustion chambers, even as much as the stock 6 - 1 exhaust headers, meaning you will actually experiance LESS power (and torque) when you use them.
This information comes from Jim Mock, and I know he has been copping a lot of crap on the forums lately, but the reason I can believe this specific information is, he would have got a stocko ford on the dyno, and simply run dyno tests (without changing anything on the dyno), first with the stock headers, then all the brands (genie, pace maker, HM, etc) then with the ones he uses, which he claims increase power the most, by having a small-diameter primary which is very long (hence allowing high exhaust gas velocity and scavenging the cylinders).
So, while his dyno might lie, it wont lie when you do the same test on the same car with just different extractors :)
TQE, SWB, ATPS, Worst of the E-series.. and I wouldn't have it any other way
That's interesting juarez, do you have a link to that info and some dyno charts maybe? Also how does the heat coating work? What is is made from? Is it porous and increase the surface area of the pipe for ventilation or something? Does it help performace by running engine cooler?
Well my old man has always run genies, so of course I run genies.
However, times change so I sort out an 'informed' opinion from one of the dudes at the local 'zost' shop (not somewhere like midas, i mean a real shop) and asked him his opinion. He said that on the xflow 250, the shortbase genies were about as good as stock and he didnt recommend them, however he has the longbase extractors fitted to his EB xflow and loves them.
