Indeed isnt that the whole point of putting a exhaust on.

Exhaust systems have different sounds, not all of them sound the same. Some have more rasp, some have more drone, some are loud, some are quiet. Not all of us put exhaust system for just some "noise". The OP is asking how to eliminate the drone, he's not complaining about the loudness.

There's a big difference between having a nice sounding system that doesn't drone through the cabin and one that does.

My Greddy Ti single pipe, single exit for my 350Z never droned. Same exhaust for my buddy's 2009/10 (can't remember the year) Lancer drones all to hell and it is annoying every time we car pool together. I'll probably just go with the Megan exhaust for my IS, as it doesn't sound too bad. HKS for every car I have ever heard has always been obnoxiously loud and had droning of some sort.

I am happy with F Sport exhaust for 3 years. It has little to no drone for me. Actually the more quiet M2 exhaust on my IS350 has more drone than my F Sport on my IS250 at 80MPH.

Like other mentioned, I think your new F Sport is breaking in and it would take about 2 weeks. The first few weeks are pretty loud and it gets quieter.

Anyways, F Sport exhaust is one of the most wanted exhaust on this forum. Tons of members would trade stock exhaust + cash with you. I know I will if you like

i had HKS Hi-Power with Invidia Mid-Pipe... it sounds great but it drones like hell on free way speed, it gets worst when your car is full load of people... sold that and now have Greddy SP Elite with Invidia Mid-pipe, no drone but miss the mean sounding HKS Hi-Power cuz the Greddy sounds like a louder G35 lol, i do miss the fun of back firing when i want too lol..

I have been on the Lexus HKS exhaust for around half an year and it is the perfect exhaust for me. There is no drone at all, and it can be loud on high revs and a little raspy. It is really really fun with my IS250MT

I used to have the Medalion exhaust and it was terrible, the drone was unbearable.

My buddy who sold me the Lexus HKS bought the SP elite and told me there was very little 'sound' from it and was disappointed. But it looks really nice.

I installed the f sport exhaust with a magnaflow resonator and there is no drone whatsoever. I think you just have to get used to the growl of the f sport coming from the super quiet stock exhaust. I drive on the highway too and there is no drone whatsoever imo.
