Rust Inside Turbo Manifold Runners?!!?

[94'TSI'AWD]

Just bought a FP manifold for my 16G and under closer inspection I noticed that there is rust in the inside of every runner. Is that bad? How do i get it out, Sandblast the entire manifold and then have it ceramic coated?

I would just take a rag and wipe it out to knock off all the loose stuff. As long as there are no big chunks falling off, which I doubt there are, bolt that thing on there and forget about it. You will have the inside coated soon enough upon installation.

Did you purchase it new from FP?
