I have the Bub slash cuts. They look good, sound good, and perform well. Only complaint - rust on right side hanger weld. They are about 90% of what I was looking for in sound. I've had stock, and short TORS, both before AI removal and jetting. I think a deeper sound is still possible. After listening to all the sound bytes here, I kinda liked the sound of the J.C. Whitney ones best. Some of the others sound awful harsh to me. After my Harborfreight bike lift table comes, I'm planning on ordering some of the JCW pipes and experimenting. I want to hear some different glass-packs, and they're pretty reasonable (not $400 a pair). I'll report my findings. Charlie
