The combo

An Akrapovic slip-on paired with Arrow head pipes is a bigger step than a slip-on alone — changing the exhaust note more dramatically since the headers are replaced too, not just the end can.

Before & after sound test

The full swap takes the Versys 1100 from a quiet stock note to something deep, throaty, and considerably more aggressive — demonstrated with a direct before/after comparison and a ride-by sound check.

Worth it?

Because this changes both the slip-on and the head pipes, it's a more thorough transformation of the exhaust note than a slip-on-only swap — worth it specifically if the goal is a meaningfully deeper, more aggressive sound rather than a subtle change.
