Took 2 baffles out of the pipes my neighbor gave me.1st one took 2.5hrs. 2nd one took 20min. Now that's learning from your mistakes! Sounds terrific. Called the dealer and no need to re-jet. Still gets enough back pressure for scavaging. After a weeks riding it's actually getting a little louder. I didn't want obnoxious. Now, I can hear it going down the highway and actually helps me keep a steady speed. BTW, I used a sharpen chisel and a long screwdriver(sharpened) to simply punch slot around the baffles. They weren't on the bike. Plus could not believe how easy they were to swap out. 15min.
Ride on all.
