Sorry for my lack of updates. After a couple weeks of riding, I'm loving this exhaust. It's definitely louder than stock, but it's not obnoxious and is fine at constant highway speeds. Tone is a bigger difference from stock, though. It's beefier, gruntier, meaner, racier. It's a bit intoxicating and makes you wanna crack the throttle just a liiiittle bit more...
I've noticed a performance increase, as well. Pulls hard without any lean spots. Though that may be due more to the excellent tune from @2wheeldynoworks.
I'd buy it again in a heartbeat.
