How do you drill out stock 2007 flht exhaust baffles and do you have to remap and how do they sound drilled out?

You can take a LONG steel pointed rod and punch out the baffles. The You don't have to remap or do anything.

It sounds slightly louder..a nice sound and the throttle response increased from a ded stop.

the baffles are not able to be removed since they're welded in place but you can drill them out or just punch through them.
