Default Intake Manifold?

I recently bought my first Corvette, its a '98 Coupe, auto. It has a Blackwing air filter and a Borla cat-back exhaust. My question is what intake manifold would best pair with the Borla exhaust and is it worth it without putting headers on first since I can only afford to do one or the other right now.

Thanks!

Personally I would do both being you will need to have a tune for each to get the performs gains and not throw any codes.
I just put a LS6 and AR headers on my 99 this year and sent the ECU in for a $149 mail order tune. Without the tune I was blowing black smoke because it was running to rich after the mods, but after the tune the HP and torque increases are really noticeable.

The later model LS6 intakes only added a few HP (10-15 I think).

Get an intake manifold from a 01-04 Vette.

LS6 intake for sure. It's pretty sufficient until you start making big power. It's relatively cheap and an easy swap as well.
