Looking at picking up an F-Sport exhaust, and just curious if anyone has had any droning on it specifically at interstate speeds? Probably looking more towards the engraved F-sport one, but from reading around, the Lexus HKS one seems to be deeper sounding/quieter so I would probably be open to that one too (along with thoughts on that one droning). Otherwise, afaik, the only differences between them is the deeper sound on the Lexus HKS, and the fact that both F-sports (engraved and non-engraved) have a straight piped passenger muffler.

Had a Tanabe in the past that I got rid of due to the droning at interstate speeds. Absolutely drove me nuts.

I've got the Tanabe just shy over a year now. There is zero drone cruising on the freeway 2.5 - 3k. Even daily driving there is no drone. I think my stock exhaust was louder when taking off from a comple stop.

Not sure what was up with mine then. Droned like crazy at 2-2.5k rpm on the interstate. Even bought a gasket replacement for the driver side muffler from Tanabe directly thinking that was the issue, drove me nuts. Thinking back, maybe it wasn't seating properly on the donut gasket but I did reseat it/reinstall it quite a few times to no avail.

From my experience, the F-Sport exhaust has a light amount of drone when cruising on the highway between the speeds of 80-85mph (approx 2600-3000 RPMs). You can mostly remediate this by being very light on the throttle if you stay within this MPH/RPM range. If you are outside of this range, the exhaust is pretty compliant when cruising at a constant speed.
