It's not the parts, it's the labor. They won't be cheap to have installed, and they'll be a full day long project if you try to do it yourself -- and that's assuming you have a lift or ramps.
I can't imagine that any stock, iron, clunky manifold can come anywhere near the power you can gain through headers. But I suppose I could be wrong.
I know these are LS1 manifolds... but look at the difference between a "manifold" and a "header"
That's a pic from when I did my swap. I just can't imagine that a manifold can come close.Former Ride: 2002 Pontiac Trans Am WS6 - 345 rwhp, 360 rwtq... stock internally.
Current Ride: 2006 Subaru Legacy GT Limited - spec.B #312 of 500

dude i know its hard to belive but i read it in a mag stating that the stock vette manifolds made only a few less Hp then long tubes. trust me it was soo hard to find long tubes for the ls1 im putting in my 67 camaro and it said that u can put vette manifolds on the ls1 conversion into a 67 and it would only make a lil less power than long tubes but it would be easier and less expensive than to put in Long tubes. ill look for the article. by the way i do know the difference between the two1967 Camaro "Project"

Only a 6 HP difference between the LS6 exhaust manifold and a good LT header is very hard to believe. Most guys see around a 22-25 RWHP gain by installing a set of quality LT's on a LS1/6 motor. Don't believe everything you read in magazines.

This is the only pic I could find online of the LS6 exhaust manifold. Small photo, but interesting. But doesn't look that great. I'd like to see the article that claims only 6HP for headers..... remember where you read it?
LS6 cast iron:
2002 F-Body cast iron (the 98's are stamped stainless steel, not CI):
Looks like the oulet is to close to the center for the LS6 to fit in a 4th Gen F-Body.Fred

Well im looking 4 the atricle now, im pretty sure it was in a car craft magazine but i got a bunch of em and its gonna take a while, and i know not to belive everything in magazines but when they prove it with a dyno..... so anyway ill post when i find it .1967 Camaro "Project"

The orientation of the outlet is in the wrong place for an F-body. As far as the power claims, that depends on what rpm this takes place. Losing 6 HP to long tubes at 5000 rpm means nothing if the long tubes generate their peak power at 6200.I will say that years ago, Brudzinski was a maker of high flow exhaust manifolds that were darned near the power of headers, but I haven't heard that name in years. not long after I got my 97, I installed SLP extrude honed manifolds that gave me a 10 HP increase over the factory parts, but I still saw a power increase when I went to the SLP shorties.

Go ahead and bolt them up and when you can't get the exhaust downpipes to work because they are inthe wrong spot, then you will see exactly what has already been mentioned.
