Seen a few do it to there IS and RC 350's and it's quite impressive. Kinda aggressive for a GS depends who you talk too but it sounds really good.

Has anyone done it to GS?

Don't for the love of god the drone is unbearable, I did it and put it back on plus there isn't much of difference in tone. The F sport exhaust sounds the same minus the drone.

This is of course if you only plan on deleting the muffler and nothing else.

 

Hahahaha ok ok ok, yea the drone must be crazy
