B18A1 noise at 3k rpms

[dyer87]

Ok so im new here.... but i was wondering if i might partake in some advice.
OK so heres my problem, no matter what gear i'm in at exactly 3k (no higher or ,lower) I get this really awkward noise coming from the engine. Its sort of like a weird vibrating noise..My only thought is it might be something with the exhaust. Well any questions or advice let me know... Its a B18A1 LS na engine in a 91 civic hatch.
thanks- Andrew
