I drilled out the primary, (center) baffle on the SE mufflers I put on my 01 Heritage. Actually, beat them into submission is more acurate. The center baffle, on the SE's, was a plug stamped out of the surrounding baffle material, then bent into position as a blocking plate. It was the only thing blocking the straight through line of the pipe. I used a sledge and a half inch steel rod to bend it back toward the original material.
Check your pipes. It may be easier to push it out as opposed to drill it. If it is a flat plug, like most of the stock mufflers, use a long, 6 to 8 inch, bit. Start with 1/4 inch and work up to 1/2 inch. That should do it. Be prepared for the pipes to be loud. BTW, the older model SE pipes used to be straight through with just the metal baffle and no packing material.
