Has anyone seen this style header before, or used them.
I hope I don't get in trouble for this.

memike, you are a treasure. Where did you find these? I've been looking for something like this for 2 years now. Dutra dual flow for half the price with half the weight? Gotta love it. There shouldn't be any problems running these on a 170 with a stock intake. Should be about like pulling the tater out of your exhaust pipe. My hat is off to you sir. I'm ordering a set of these as soon as I can get back on my feet and talk the missus into it. That shouldn't take too much longer since I am down to one crutch and I bought her a sewing machine yesterday.
All good points, but we are talking about an engine whose best exhaust at this time is a hacked up stock manifold with an additional cast iron manifold that has none of the virtues you describe, and you will pay around $400 for the privilege of running it when the supplier deigns to send you one. Your other options are high priced headers that may or may not be available or fit, and have no real flow benefits until you reach revs that stock slants refuse to go to. Gotta remember that the crank goes into terminal harmonic shake at 2250 RPM (4 main bearings). Slants are not high rev screamers so a lot of the popular header design is out the window. The real power killer is the exhaust manifold (I've cut one up) and any improvement over stock is welcome. To find that for a reasonable price is rare.Could be wrong but i see no scavenging effect and pulse reversion on these. I do not think personnally there would be any power gain. Probably a loss.Primary lenghth and collector size contribute significantly to the power band.These look like a dump exhaust and would kill low end although they may show power gains on the top end.Theres a lot of science involved in a good set of headers. The pit stop section of the September 2007 issue of Hot Rod magazine covers this in detail.

With all said! I like the PowerPipe-DC headers.
They are light, and work with the factory intake,
I am not the sharpest knife on the shelf but I do know one thing
for sure, These are just what the doctor ordered for me.
and will out perform a single heavy cast iron exhaust.
And I will get me a few hp and better on gas and a great sounds out of the dual exhaust. At 250 dollor at my front door.
This will be a driver and spoiler for me, not looking to put to much hp to the trans or rear end. Stock Baby Stock.
Hey Mike,
Not here to sway you one way our the other,just trying to help.I have been playing with the slant motor for many years before I came over here to play with my V8 car.So I know of what I am talking.First there is no proof (other than word of mouth)that this(I wouldnt even call it a header)exh manifold will even out perform a stock exhaust manifold.
