Are the baffles in the SE II Pro slip-on's welded in , or what ? i want to pull them out to drill out the holes from 1/4 " to 5/16 ". ive heard this will give them a deeper tone.
anyway... i cant get them to budge. whats the secret ??

 

Not sure if this is the same. My SE pipes have like a set screw that goes in from the back, not the bottom. I had to unscrew the bolt out of a welded on nut attached to the baffle. I don't know if this helps.
