HKS Legamax drone?
 

I have a 2014 GSR and it drones at 80mph in 5th gear. The car is stock and yes, it drones at 80. 2008 and 2010 have different mufflers than 2011+ and the new ones definitely drone around 3800 RPM.

In a quest to get rid of that, I am seriously considering an HKS Legamax axle-back exhaust. But will it fix it? Countless posts are on here saying it is quiet and also not worth it but I'm trying to keep the car basically stock so a 3" turbo back exhaust and running 11's isn't what I'm after.

So owners of the HKS Legamax axle-back, does it drone at 80 MPH?

While I don't have the legamax, I have the Hi-Power L-Spec, and it does not drone at any RPM. I do have factory cat still though.
