Hello,
The 04 and 05 GTO use the same exhaust manifolds (5.7 LS1 & 6.0 LS2).
The 03-05 SSR's/Trailblazers all use the same exhaust maifolds as well (5.3 LH6/LS4 & 6.0 LS2)

Yeah, thats the #'s according to the GM Catalogs. (i'm a Parts salesman at a Chevy Dealership 
)
I agree, it kinda sucks to have the same maifolds on a higher output engine.
5.7 -> 6.0 is not that big of a deal - it's the 5.3 -> 6.0 that I would worry about.

There is a post about low dyno #'s from 05 GTO's. Maybe it's the manifolds and a good set of long tube headers will wake it up.
If this were the fast and the furious site, my guess would be at least 100 rwhp.

Yeah, I just found a picture of a 2005 GTO LS2...you're right same manifold.
Those things have to be choked up, if for no other reason, the fact that those manifolds are smaller than the vette's and f-body's manifolds.
The C6's manifolds flow 1/3 more air than the LS6 manifolds, by reducing the pipe thicknes from 4mm to 3mm (essentially a ported manifold).
Well, looks like I'll be trying to retrofit C6 manifolds to my goat...they're no long tubes, but for 1/10 the cost, I'll take it if I can get it.

If your not getting longtubes don't waste your time as you won't see much of a gain if any IMO.

Well, the Mac's wouldn't work with a GTO and shorties that would are $500+
It's also kind of an experiment...I'm curious how much more they flow and have access to a dyno...besides, working on a car is fun for me, so if it doesn't work out, no big deal...if it does, well, I'll let you know.

I bought a pair for my conversion project from direct gm parts place online and I think they were a little over $300 for the pair delivered. They are really nice. A full 2 1/2" outlet, light weight and big primaries. I have a set of the gto manifolds that I had purchased as well thinking they would fit on my car. Man, am I glad they didn't. The gto mans have <2" outlet.
