It says above it's advisable to get the ECU remapped. I was hoping it was the down pipes too (to avoid the rusty look on the front down pipe), but it's clearly not included as the picture seems to show what looks like the lower LHS header to exhaust join being where it ends. Don't really see the point of de-catting and needing a re-map - it's not as if it doesn't sound good and loud enough already, and it's hardly a slow bike.
