I have an is350 fsport and i installed the remark axelback, first of all. Its great. Now about the horrible drone from 2-3k rpm . I found a way to make it way. Way better.

if you have the asc **** in your f-sport model when you turn it up it kind of cancels out the weird frequencies in the cabin!!! And instead of an annoying drone you get a pleasant exhaust sound.

so give it a shot 🫱🏼‍🫲🏻

 

I had honestly forgotten that these cars have these lol. As in my case in the is500 i highly doubt this will work but we'll see lol

 

had a similar experience putting the remark on ours. i had a shop cut out the straight portion under the trunk and add in some vibrant resonators. i think i got 9-12" ones and they def help with the drone. if i did it again i might try to find some slightly longer vibrants and put them in for a slightly better reduction in drone but overall i think it sounds pretty good and drone has been reduced to tolerable levels, really only get it if youre really on the throttle.
