Professional Products Intake Manifold
The 2000 LS1 intake manifold has the EGR going into the top. If the EGR has been removed, then it should have a plug in the top. The LS6 has no EGR provision that I'm aware of. At least no LS6 intake that I've ever seen people actually use.

I think it went along the lines of:
"hey let's make a manifold for LSx engines. would bea good product to bringto the market"
"here's the finished product. we have a pretty good price on it, but it didn't perform as well as we had hoped."
"let's just.. not compare it to the factory LS6 manifold.. we have too much money into this to show how close a head to head comparison is."
"crap.. people found out.. what now.."
but.. I could be wrong <-- disclaimer statement

I think it didn't show the results they were hoping for on stock applications BUT,
They still haven't shipped out the 85mm TB's to match the intakes and I'm looking forward to seeing the results from a little porting on the intake runner entrances.
I think the 85mm PP TB will outperform an LS6 with aftermarket TB and the ported runners will yield some nice results since it will look much more like the LS7 intake after porting.
The jury is still out on this awaiting the new TB's and more dyno tests... that's why this thread is dragging on with nothingness.

I would not be afraid to say that we probably now offer the highest quality aftermarket throttle bodies available.

Pros: Pretty, nice fuel rails, cheap price, metal (alot safer for the spray)
Cons: Metal (heat soak does matter), no dyno results, but i bet it wont out perform a stock ls6, and it has not been releases yet.

No, the good version that we want, the 96mm, has not been released. That's the main subject of this thread as far as most of us are concerned. Not the 80 or 85mm or whatever it is.

I'm sorry, i read 16 pages 
and didn't have any new info.
What kind of gains could i expect on a near stock 98 auto T/A?
Stock TB, stock heads, stock everything except a SLP lid and pacesetter LT's

Just read the ENTIRE thread. Not sorry, just tired. lol Will buy the polished intake and 85 TB eventually. Hopefully by then all the trouble areas on install will be worked out.
Young, it's already in my wish list.
