It's an Akrapovic full open line exhaust
if you have neighbours don't get this exhaust lol
I have the night rod special (basically a blacked out vrod) on what they call a stage 2 with power commander, heavy breather, some engine bits, and a full exhaust (saved over 30lbs in weight)
Honestly the bike is phenomenal, fastest production harley and significantly faster than the CVOs (breakout included) and many sport bikes at speeds under 180km ish
The revolution engine is designed to reach peak power at high RPMs but it's also a torque monster from knot to 100km, and that fat 240mm rear tire gives it a ton of traction
I keep up with 1000cc bikes and basically any 600cc, twisties are tricky but you learn to push the bike and always catch up in the straights
I think most people I ride with will agree I have no problem running with the big 1000cc+ bikes on twistie roads (at least I think so lol)
