2009 G8 GXP - SLP Loudmouth Axleback Exhaust

Video of my 2009 G8 GXP. Bone stock, except for SLP Loudmouth Axleback Exhaust. Simple bolt-on procedure. Sounds very good for the money, but the drone is nearly unbearable above 60+. It goes away in 6th gear around 85 MPH, but I can't drive 85 everywhere!
