must be an older Z owner.
i DD my Z and hated the car's sound until i got the FI exhaust.
it's the way to go and the drone isnt bad as you describe.
when not running the FI striaght pipes i run the full non-res TP/CBE with CF mufflers setup and theres some drone at the 2.5k-3k area as there is with pretty much any exhaust on the Z. its just a resonance point with the engine rpm and the exhaust.
