I've done it on my car, but did it with a slew of other mods...I would expect the intake is worth about 5 hp...as it was put on all 01 cars, which inreased the power about that much...of course, it might be less as 01+ cars might have gotten additional power helpers...

97-00 C5s = 350 RWTQ
01-04 = 375 RWTQ
...w/ MN6

The above also factored in the addition of "pup cats" on 01-up which raised exhaust backpressure 5 mm-HG.

My guess is you will see 15 - 20 RWTQ.

Many LS1 enthusiasts are now going FAST intake - so you should be able to pick up an LS6 manifold for pretty cheap used.
