I call this exhaust Version 3.0 as I believe this is the third development of it. This is the only exhaust they are currently selling. We pre-purchase guys are calling it the sport version because we had to endure the previous race exhaust. The only area that may have a little drone is the dreaded 1750-2250 rpm zone. Idle is very smooth, cruising at 55-80 is great, very low hum.
