Well I have had the factory exhaust on the bike for a week now. Took an adjustment to relearn the bike / exhaust sounds. At my stage in life I prefer the quiet exhaust note. But, if I feel like being a bad boy, half an hour and the Cobra exhaust can be back on. Nice to have the option.
Found I had a tendency to lug the motor a bit with the Cobra on just trying to go unnoticed and not annoy neighbors. Had a 6 hr run today and didn't get noise fatigue.
Next time I feel like a teenager, the noisy stuff is back on. Lol
