Drilled the baffles out on an '07 Nightster. No backfires, no decel popping, and sounds like an XR750 flat tracker.
The closed loop EFI on '07-up motors will compensate for exhaust changes. Install a better breathing intake with freer-flowing exhaust, and a remap will be needed.

This is why I want one. I can pay once for an EFI module (fuel pak in this case) vs. a $150 a pop for re-mapping every time I change a part. I want to do all my upgrades in stages over the next few years. I can't stand it when my dad has a louder, faster '02 Softail! Getting a bigger bike would be the cowards way out and not as fun.

Yep, at least on an '07 & up. Now, that might not hold true if you install a set of 25 inch long "Look-at-Me" pipes, but the typical (practical) pipe change should be handled by the closed loop EFI. That said, a re-map will pull some more power, but it isn't necessary (as in needed for engine protection).
