I got my pipe installed today and it sounds just a bit louder than the Factory with the insert taken out. I thought I would be setting off car alarms. Not sure why folks say it is so loud? I took the AIS and EXUP out as well. Added Zeta guards, Pro Taper Contour bars and the 12 O'clock running light and turn signal adjuster. The Bike feels better, but I really thought it would be louder. I had a DRZ400 with Yosi that would set car alarms off.
