I disagree. I spend most of my time in 6th gear at around 65-75. The car sounds fine at this RPM. Once you dip under 60mph, then it starts to drone but I'm downshifting into 5th by that speed. I daily drive the car. I had a catless, turboback exhaust SRT-4 before this car, I know what drone is.

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.

Do you also run TPs or HFCs with the FI exhaust?
